New open source full-featured Git client for Mac

Hmm I thought this would be a bigger deal on HN, especially considering how much commentary there was[1] when the limited, sign-up only pre-release version was announced.

I was hoping there would be, too, because I am clearly missing something(s) about why GitUp is so great.

In particular, how is this UI:

...in any way better than this one:

Isn't combining multiple views of different interconnected bits of data the main thing that (can, if done well) make a GUI more powerful than the command line?

I only played with GitUp for a few moments, and perhaps importantly my current project is at this stage a one-man show with a basically linear set of commits to master, but I nothing jumped out at me as to why I would use this instead of SourceTree.

Is the appeal of GitUp mainly the esoteric features like "Swap with Parent (Move Down)"?

Why are so many people raving about GitUp on the interweb tubes is basically what I came here to find out (but didn't).

EDIT: OK, a lot of the special powers of GitUp are spelled out in pretty good detail here:

My 15-minute take seems to be that it has a worse UI than SourceTree for a typical (for me) git session that consists mainly of code-review-commit-repeat, but it is especially empowered for doing things like rewriting commits already committed, or "splitting commits".

Congrats on the 1.0, this is awesome! I love GitUp, and the source code looks clean as well. Some pointers to the good bits:

The downside is that the project is now in "scratch my own itch" mode:

So this is not going to be a commercial Tower.app killer (sadly, they deserve it :P - data corrupting bugs aren't being fixed etc. - but I guess SourceTree being free doesn't help the market.)

Does it support Git Flow? I couldn't really tell by looking at the repo or the site.
