Because that git for example and the other version control systems, have a lot of commands which could be used in the editor too, we need a dedicated popup with most common VCS operations as WebStorm or IntelliJ has: https://www.jetbrains.com/help/img/idea/2016.3/refcard_3.png

Right from the editor itself, it is possible to choose any VCS option, withoug using the context menu (On smaller screens you have problems, if you have a lot of stuff in the context menu). And without selecting the project -> right click -> search for git (e.g.) -> select the operation -> select another operation and and and. It is to heavy and user unfriendly.

The Team menu entry is ok but a dedicated popup like go to symbol, file and so on, would be better, because you don't have to switch with the mouse between your editor and the menubar.

Here is a little video from WebStorm too: https://video.twimg.com/tweet_video/C5XFT7hWEAAR2jg.mp4
