I used to write stuff down, but in my case on sheets of paper that got filed with the project. But I kept thinking "Dammit, I know I've met this problem before, what was the solution?". Doing the same note-taking thing, but using the PC instead of paper, makes it searchable. You're right about the mind-map diagrams though.

Yeah I have plenty of pages filled with the project. Not having them searchable is a pain, but every time I've tried to use vim for it, it ends up being a bigger distraction than the ideas themselves.
