I'd love to like the desktop app, but I just don't understand what it's doing under the hood when I click a button. When I click an icon, is it syncing my changes up as it pulls down, it just pulling down? I guess point and click is more scary to me when prod is on the line.
If I may shill for a moment, that's something I like about sublime merge - the buttons mostly map to git commands, and it has a nice log showing the commands it ran and their output.
