A suggestion, need a "Return To Game" tab in the options menu. This is so you don't have to go out to the main menu to return back to game.
Thanks for the feedback. Notice that you can return to the game by clicking the 'red cross' button located in the top right corner. This is consistent with the rest of the dialogs in the UI, though we'll discuss with Mauricio whether it makes sense to add a button, as you suggested.
Sorry for the late reply! For the moment we'll leave it as it is. Once we start getting feedback during the open alpha we'll decide what to do. We don't want to start acting on all the feedback right away until we have more data points. But thanks for the suggestion, please keep them coming!
