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.
no problem on the timing of the reply, I understand you guys are busy. Looking forward to more updates:)
Apologies for neglecting to answer this question! Notice that you can always enter a numeric value in the text field. Or you can press the left and right arrows: if you only press them once, the modules will rotate by one degree, which should give you enough granularity to achieve what you need.
