I was doing a trial run of git GUIs cause I'm much more productive with one and I landed on Sublime which was good but lacked a lot of options and I don't think still allows for adding custom commands. I was also extremely miffed when it took months for an update to come out to fix one bug I'd found and was irritating me to no end (I forget the specifics now). For me the update cycle is also extremely slow and the price is prohibitive.

I wish I liked it more but I've settled on fork now. Good you're happy with sublime. I'll check it out again once it's rounded off with more features

This looks awesome, and fully native too it seems! I'm not a fan of the electron style git GUIs that don't really fit into the OS.

In the case of OP, Guitar looks a hell of a lot better on Linux installs. I suppose that's due to QT theming.
