What if there could be more than one, though? Only a few things would have to be altered, it seems to me, and this could be done at a single point (the simplest being to designate a folder as the current Draft or Manuscript folder). This would ripple through the data structures of the project, I believe mostly affecting what gets compiled and how it gets compiled (styles, templates, etc.). You would only be able to access those things for the current Draft; the alternate Draft text folders could be accessed for editing but nothing else.
Vincent is right. There are multiple ways to do this among them is putting other books in folders inside the research folder, or as separate projects per book. You can easily refer to important scenes with both projects open. I have a 3 monitor set up and have projects often open on at least two screens at the same time. you can also drag critical scenes into an Old Scene folder in your research folder to refer to or bookmark in current book. you can also have folders for each book in a series in the draft folder, but uncheck them for compile so will not show up when compile current project. That is just scratching the possibilities. I also have a series bible with the world building and character info across the series as well.
I was just thinking it would be nifty if there were a way to do it easily, naturally, and quickly (this would also minimize the result of leaving out a step while doing a complicated, multi-step switchover for the umpteenth time).
There can only be one Draft folder, but you can create as many subdivisions as you like within it. You can then Compile whatever combination of subdivisions you like, using the Compile Format most appropriate to the intended destination.
Could you clarify what you perceive to be involved, please? It seems to me that if you wanted different section types for the shorter form, you would only need to assign those once, and then assigning those types to a given set of Section Layouts would also only need to be done once.

Human genes encode long precursor messenger RNAs (mRNAs) that are extensively processed before nuclear export. This maturation includes the splicing of exons, which normally occurs with high fidelity to create functional mRNAs1. Constitutive exons splice into all mRNAs transcribed from a gene, while alternative exons are sometimes included and sometimes skipped2. Human protein-coding genes each produce an average of three mRNA isoforms through alternative splicing, many of which are differentially regulated3. RNA binding proteins play a key role in transforming precursor RNAs into mRNAs. Although RNA-binding proteins can regulate many transcripts in parallel, some splicing regulatory proteins preferentially engage with transcripts belonging to specific functional classes, including Nova proteins (synapse functions), Fox proteins (neuromuscular, cytoskeleton and EMT functions), PTB proteins (cytoskeleton functions) and T-STAR (synapse functions)4,5,6,7,8.
Tra2 proteins have amino- and carboxy-terminal domains enriched in arginine and serine residues (RS domains) flanking a single central RNA recognition motif (RRM) and so resemble the relatively well characterized core group of 12 SR proteins that control both constitutive and alternative splicing as well as other aspects of RNA metabolism23,24,25. Each core SR protein contains N-terminal RRMs and single C-terminal RS domains. However, unlike the core SR proteins all current data implicate Tra2 proteins solely in alternative splicing rather than constitutive splicing10,26, and only SR proteins and not Tra2 proteins can provide splicing activity to S100 extracts26.
To regulate splicing inclusion Tra2β binds to AGAA-rich and CAA-rich target RNA sequences. These RNA protein interactions have been resolved at the atomic level9,27. Endogenous Tra2β target RNAs have been identified using HITS-CLIP18, RIP-seq28, shRNA depletion29 and microarrays17, but important fundamental questions still remain as to the identity of the biological targets and the functions of vertebrate Tra2 proteins. These include whether endogenous Tra2α and Tra2β proteins jointly control the same splicing targets, and if so what these shared targets are? Although Tra2α and Tra2β both activate splicing of the same model exons when overexpressed in transfected HEK-293 cells (suggesting redundant functions)18, the Tra2a gene alone is not sufficient to maintain viability in Tra2b knockout mice (suggesting specific functions)15. Another question relates to how Tra2α and Tra2β interact with each other? We previously found that Tra2β protein binds to a poison exon in the TRA2A gene to activate poison exon inclusion18. Poison exons introduce premature translation termination codons into mRNAs so as to inhibit translation of full-length proteins and are often regulatory18,30,31,32, but whether Tra2α might reciprocally control Tra2β expression is not known.
Here we address these questions in human MDA-MB-231 cells that model invasive breast cancer. We find asymmetric splicing feedback control pathways between Tra2α and Tra2β that buffer splicing defects caused by depletion of either Tra2α or Tra2β protein alone. Overriding these feedback control pathways by joint depletion of both Tra2α and Tra2β globally identifies Tra2-dependent target exons, and reveals critical roles for these proteins in DNA damage control and cell viability.
To test for in vivo interactions between Tra2α and Tra2β proteins, we monitored their expression levels using western blots. Consistent with predictions from our previous study18, Tra2α protein levels were normally very low but significantly increased after small interfering RNA (siRNA)-mediated depletion of Tra2β (Fig. 1a top panel, compare lanes 1 and 3, and Fig. 1b). Although weak, the Tra2α western blot signal was of the predicted size and was almost completely eliminated following transfection with a TRA2A-specific siRNA (Fig. 1a top panel, compare lanes 1 and 2). Tra2α protein depletion had less effect on Tra2β protein levels (Fig. 1a, middle panel and Fig. 1b). Western blot analysis confirmed this effect for two independent sets of siRNAs targeted against different parts of the respective mRNAs (Supplementary Fig. 1).
Consistent with Tra2β protein repressing Tra2α expression via poison exon activation, siRNA-mediated depletion of Tra2β led to strongly reduced splicing inclusion of the TRA2A poison exon (Fig. 1d, upper panel). siRNA-mediated depletion of Tra2α protein led to a smaller but detectable effect on splicing inclusion of the TRA2B poison exon (Fig. 1d, lower panel). Analysis of TRA2A and TRA2B steady state mRNA expression levels by quantitative PCR confirmed that each protein also negatively regulates the expression of the other at the RNA level (Fig. 1c).
RNA-seq of MDA-MB-231 cells indicated that the TRA2B gene is expressed at much higher levels than the TRA2A gene (Fig. 1e shows one of three biological replicate RNA-seq analyses, with the height of the y axis showing read depth and so indicating relative gene expression levels). This provides a potential mechanism for why Tra2β represses Tra2α protein expression more than vice versa, since lower cellular concentrations of Tra2α would be less able to activate splicing of the TRA2B poison exon.
These data are consistent with maintenance of splicing patterns via paralog compensation, that is, following depletion of Tra2β, upregulated Tra2α is able to functionally substitute for Tra2β and largely maintain Tra2 target exon inclusion. The Tra2β target exons inhibited more substantially by joint Tra2 protein depletion compared with single depletion of either Tra2α or Tra2β included SMN2 exon 7 (Supplementary Fig. 3), which is a candidate target for gene therapy in spinal muscular atrophy20.
(a) Scatterplot showing amplitude of splicing response of 53 exons to joint depletion of endogenous Tra2α and Tra2β in MDA-MB-231 cells. The genes corresponding to the highest amplitude PSI changes after joint Tra2 protein depletion are labelled and highlighted in red. (b) Analysis of Tra2β binding site density (measured as a percentage of exon content) within groups of Tra2β target exons identified by iCLIP. Tra2β binding site density comparisons are shown between the Tra2α and Tra2β poison exons; all exons that showed a greater than 15% point PSI change following joint Tra2α and Tra2β depletion; and in the exons that bound Tra2β based on iCLIP tag coverage but did not respond to Tra2α and Tra2β depletion. Probability (P) values were calculated using an independent two-sample t-test (statistical significance: *P
Since our panel of splicing factor knockdowns was not exhaustive, we cannot exclude all combinations of combinatorial control. However, our data are at least consistent with Tra2 proteins being among the most quantitatively important splicing regulators for their individual target exons.
(a) GO enrichment analysis reveals splicing targets responsive to endogenous Tra2α/Tra2β protein concentrations are enriched in particular biological processes associated with chromosome biology. (b) GO enrichment analysis showed some joint Tra2α/Tra2β-responsive exons were annotated to multiple overlapping biological processes. (c) Summary of GO and network analyses of joint Tra2α and Tra2β-dependent splicing targets. Individual segments of the pie chart show the percentage of Tra2α/Tra2β target genes directly annotated to the GO biological processes shown in part a; the percentage of Tra2α/Tra2β target genes that interact within the BioGrid database with partners known to be involved in the biological processes shown in part a; and the percentage of Tra2α/Tra2β target genes, which have unknown or unrelated functions. Full details of the BioGrid analysis are given in Supplementary Fig. 4.
