The git integration sounds brilliant and reminds me of Fusion 360's timeline functionality with which you can go back to an edit you made, change something about it and have the change propagated through all later edits: Sounds a lot like rebasing!

Now that you're promoting it and still calling it "alpha software": Are you putting effort into polishing it up? Doesn't make mucb sense for people to invest in it if it's going to remain in alpha state, after all (though it seems like you're using it successfully, so maybe it's not that bad?).
