For a while my method of taking and organising personal notes has been pretty chaotic. Mostly it consists of a bunch of badly-named text files open inside Notepad++, which aren't organised at all, aren't saved properly and aren't backed up. I hit 100 individual files recently at which point I realised I should probably change something.

I'm not talking about 'proper' documentation - that goes in a wiki, and is readable for everyone. But web-based wiki editing is slow and clunky (compared to just scribbling in an open text window). This is more for personal notes that come up during development ("remember to deal with X edge case", "consider refactoring Y", "Z looks like a bug"), most is for short term attention (say, this week) but some will be lower priority and get put on the mental backlog. But without proper organisation they tend to slip into the void.

I've also replaced my paper notebook with a Kindle Scribe, which is great but again it's not very good at organising/cross referencing/searching. And a long time ago I used OneNote on a tablet, but I have no idea if it's still decent and I'm not keen on getting a 356 subscription just for that.

It feels like there should be something between the heaviness of a wiki and the raw chaos of text files. What do you lot use? Thanks.
