This is a great app, but I'm an old dude and the angled text makes my brain hurt if I don't tilt my head, and it makes my neck hurt if I do. On top of that, sometimes it's truncated at the top of the window.
I'm happy to scroll to the right if I can see the branches/tags as horizontal text in their entirety. I would love to get the option to see that horizontally. I gave it a go once, but I'm not a mac OSX developer and I'm not too sure what I'm doing.
