I'm not currently working on any personal projects, but at my job I'm constantly juggling several projects whose priorities keep changing. And for many years I've been doing exactly what you do - keeping logs in text files. Long-running projects get their own text files while smaller projects get recorded in a "daily log". I like text files because they're easy to grep for keywords, and because a simple text editor is free of distractions.

I find that this is even useful in the short term: if I'm working on some code and need to go to a meeting, it's easier to get back into the code later if I have a record of the last thing I did before I was interrupted.
