Aah good old Tiddlywiki. I’ve used it in the past but totally forgotten about it. I’ll give it another look when I get time, looks like an interesting solution.

Correct, if you choose to put numbers in your file names. My advice is to do that with caution — if you do it to every file you’re adding an overhead that probably isn’t useful. The main use-case is being able to see the file name in a list of ‘Recent’ or ‘Currently open documents’ and for that to be useful to you.

If that _won’t_ be useful, I think adding the number is a waste of time. (Unless anyone else has another use-case?)
