How I spent the last couple of weeks (part 10? 11?):
I used jj aka jujutsu a lot. Basically I use it for all of my repos that do NOT have git submodules.
I really like the workflow, although my muscle memory leads me to type git commands sometimes. And I need to come up with a set of aliases like have for git. "g" for "git status", "gp" for "git push", that kinda thing.
I am looking forward to the further developement of jujutsu and can hardly wait until it includes submodule support!
