I would DIE for a gui
here's the thing
I create lots of well-sequenced, very intentional commits. They are small and repeatable, so it makes it easy to handle rebase conflicts. Just read commit message, see original diff, and 80-90% of the time I believe anyone should be able to see what the original commit was doing and resolve conflict such that same thing is being accomplished on new base. Almost each commit could be one PR, but maybe sometimes it's better to group few commits into one PR.
I'd like to create a PR stack so that it's easy for others to review my changes, but, I don't want to mess around with git branches locally at all. I'm already a surgeon with rebase.
Ideally, I have a gui tool.
