Often work on several projects at a time here. Keep two text files on the desktop to sort them out, one small file (~200 lines) for concrete ideas and another large file for "future" or less defined thoughts. Inside each are project code names and a list of notes underneath each one. That way it's easy to add and keep additional ideas to the project, but doesn't require me to log in to a project management app, commit to a repo, etc. An unexpected benefit of keeping ideas from many different projects in single files is that an idea from one section often leads to an additional feature for another project.
