I would like to be able to add notes to a branch.

I would like to be able to edit the notes later, and delete them if need be.

WHY?

I find that I frequently get interrupted and have to switch between different deliverables. I use GitFlow and so switching between feature branches is pretty easy. The problem is, sometimes I will go back to a feature branch and I don't quite remember what I had completed or where I was going with the current changes.

I do typically keep decent reminders in a notepad or text file, but I think it would be nicer/better if I could just do this on the branch in source tree. That way it is all contained together.

I am NOT saying it should be committed in the repository, or stored indefinitely. I'm thinking of this as a sort of scratch pad, to keep thoughts, ideas, progression notes for the current branch. I'm thinking of this as some sort of meta data that is associated with just source tree and the branch in question, and once the branch is deleted, so are the notes.
