Like this. The main content is in the middle, with more or less the same stuff on the right as in the new tiddly, to search, list tags, list everything, etc. On the left is what was useful every day, a list of fixed links. I had one for each day of the week, for mornings, evenings, etc for checklists, links for programming language tiddlers, links to various reference tiddlers, for easy access. It was always there, and quick to get to something like a list of Greek letters or the end of day checklist. These links were defined in a Menu tiddler. The very last link was one to bring up the Menu tiddler itself for editing. Life was good, then the new tiddly5 came out and this left column feature vanished. Is there a plugin that restores it?
BTW, for anyone who says to just use the classic tiddly, I did, but then one day it stopped being able to save itself. I couldn't save changes to my info, due to iirc changes in the browsers or security or some such. If it's possible to get classic to work properly, I'd keep using it.
