This was not anything I proposed. I said we might have an ingame shift-tab overlay like steam to easily access RTB connect/mod manager/other features from ingame.
What I meant was a steam-like overlay, but now that you put it that way with RTB Connect and Mod manager it sounds good.
It probably would work even with steam* too, right? And changeable overlay key?
*As in steam overlay, not RTB Connect using Steam, because that'd kinda be tricky and could be open to steam hackers.
