My group and I don't use VoIP, because we find text chat more immersive. We were stunned to find that the GM Mode won't let you use text chat (apart from the "out of character" chat in the bottom left)!
Please, please, please Larian, implement:
1. in-character chat, which pops up above the speaking character's head;
2. let the GM do this for any possessed character;
3. ideally, also let the GM "throw" their voice onto any spot on the scenery, having text appear there.
I am sure that this would not be too hard to implement! Most of the code must already be there (e.g., for damage numbers, etc.). So please, please, please implement this. As it stands, for those of us who don't want to use VoIP, GM Mode is a total bust. :(
