I keep README.txt files in the project folders with a line that reads --CHANGELOG-- above the stuff that was, above which in turn sits the stuff that yet wasn't. I use punctuation as labels (+/- #/= %/$), and more rulers like --INBOX-- if I have a lot of ideas. I use many of those lists, a couple of which I revise daily or several times a day, those are my main INBOX.txt and FOCUS.txt
