git-todo maintains a local per-branch todo list to keep track of what you want to do on each branch before you feel ready to push it upstream.

Put in your path, make sure it's executable and run git todo from a git directory while not in a detached head state. It will launch a text editor for you to enter whatever freeform text you want.

With the -p argument, it will instead send it to your pager so you can see the branch's todo in the terminal without editing it.

git-todo will check for the text editor by looking for the environment variable $TODO_EDITOR, then $GIT_EDITOR, then $EDITOR, and fall back to the standard editor, ed if none of the above are set.

Similarly, with the -p argument it will go through $X_PAGER environment variables before falling back on cat.
