Actually, by the time the user has reached this amount of proficiency with OpenCS, he will probably just press the return key (we have nearly full keyboard support after all). Anyway, do we have anymore opinions on left-to-right vs right-to-left? If not, I will invert the order. Not particularly invested in this aspect of the layout.I understand the idea of placing the most used icon the closest to the left, but I think that once people get used to clicking the the right-most icon because they use OpenCS a lot, the time spend between going to the right with your cursor or not will be nullified anyway. The thought of placing Edit Addon left-most and New Game right-most just seems structurally wrong to me.
btw. it is "Edit Content File", not "Edit Addon". Editing for games and addon share the same UI and therefore also share a button.
