I agree on what have already been said. TW is amassing in so many ways but has some pitfalls.
On my list of frustrations wit TW I agree with @Rich
1. problem: mobile capture.
It is a big problem. As said
elsewhere the future of computing and note taking is moving to mobile devices. For me the roadblocks here is:
a. speed. Of course it also has to do with the power of the device, but other note taking tools have no problem where TW5 struggle.
b. buttons is a bit small to hit, thus making capturing a bit cumbersome.
solution proposals
If tiddlywiki could watch a folder of txt or markdown files and automatically import them, TW could be used to view the files and make nice tagging, and whatever app that is better optimized your device (and outputs in txt) could be used for capture. This would preserve the TW portable file strategy and make it more flexible.
Another path could be to make some other app (optimized for mobile devices (e.g. AndTiddlywiki)) create a tiddler in the TW without opening TW.
Of course performance improvements is always in it self. @Mat I am looking forward to try the plug-in.
I experimented a bit and found out that by purging my TW5 for photos and keep the size down ( to about 6mb) I cut the android loading time by around 30%, but the biggest difference came when I disabled as many plug-ins as possible. this reduced loading time by 50%. But TW is still a bit slow.
2. images. it is to much hassle.
@Mat
There is a quite nice image capture feature already. When you press the import button on a mobile device, you get a dialogue asking if yo want to import a file, a picture from gallery or take a photo with the camera. This is great. For some mystery it works on my work phone Samsung android 4 but on my private LG android5 it doesn't (but others have reported android5 success in the forum).
However there are two problems with images in my opinion.
a. if you want to keep the size of the wiki down you need to keep photos external and it is clumsy to write links.
b. It takes to much time to give photos there own tiddler and the transclude them.
solutions proposals
it would be great if you cold drag´n drop photos into the text editor of a tiddler and then either include it as a link to a image tiddler or a link to the external photo (e.g. with a save dialog), in that place in the text.
This is just my ideas of solutions. I am not a programmer. If they are technically feasible or not, I am sure others have greater knowledge of.
