started tracking todos for my programming side projects by just making a little (usually untracked) `todos.md` file in the project's directory and it's so much better than anything else I've ever tried
@b0rk this is great (I often put a section like this right in the README.md). I also tend to add a "journal.md" to each project where I just ramble as I work so there's at least some record of everything that doesn't quite make it into the more organized corners of the project.
