Add option to show button label for newcomers #2828

Hi, recently i'm trying to find Source Tree alternative in Linux (i'm using fedora), so i'm new using Source Git. But the very first real hassle to use it is there is no label for every button in the UI. Can we add option to add it? i know it needs UI redesign for that, but i think it's worth it to develop because it will make the new user easier adapt to the UI. Thank you.
