GitKraken has a dropdown menu that appears whenever you drag and drop if it involves two elements (ie merge, rebase, create GitHub PR), as well as right click if you're operating on one element (ie creating branch/tag here, reset soft/hard). Double left-click to checkout a branch. There are big buttons at the top for fetch/pull/push, and when staging a commit there's a clean and focused view for choosing which hunks to stage. Basically all needed operations can be initiated with minimal mouse actions, and anything destructive has a confirmation.
