Been using cline and their snapshot/rewind/remove context (even out-of-order) features are really shining especially with larger projects and larger features+changes becoming more commonplace with stronger LLMs.

I would recommend you check it out if you've been frustrated by the other options out there - I've been very happy with it. I'm fairly sure you can't have git-like dag trees, nor do I think that would be particularly useful for AI based workflow - you'd have to delegate rebasing and merge conflict resolution to the agent itself... lots of potential for disaster there, at least for now.
