How well does your integration handle stacked PRs (if at all)? I find that the majority of my interaction with git is super basic that I get no value add replacing `git add -p` (esp. since I'm always in my terminal with Vim/tmux). What _is_ annoying and something I could probably automate if I thought about it for more than a few minutes is when: a) I have stacked PRs for isolation/workflow purposes in the form of: A <- B <- C b) we use squash and merge c) now when A gets merged I need to fix B and C because while the change set is the same the history is not (because of the squash & merge) d) when B gets merged I have to fix C for the same reasons
