Does it show a GUI, analogous to [1], or tell me to sort it out myself on the command line? I'd it's the latter then that's very much giving up. On the other hand, it's possible I'm mixing it up with some other GUI I tried.
If a rebase encounters conflicts, it tells you as much, puts every piece of the commit that it could auto-merge into the index, and adds conflict markers to what it couldn’t in the working tree. Then it’s up to you to merge them in an IDE or Optionally (I think) choose yours / theirs for each hunk. Once everything is resolved and moved to the index, “continue rebase” goes on to the next commit.
I think it’s had a rebase GUI since I first started using it in 2013. It may not have had one back then for interactive rebase, or else it didn’t work for me, but it does now.
It’s not as nice as that one. I described it in my other comment. The workflow is okay, but that visual context of to/from branches in your screenshot is something I wish SourceTree had.
