might actually make it worse, sometimes a t will accidentally stand up not intending to use chat, maybe drink some water, I think adding this feature would actually increase free kills because of inexperienced ctsLot's of idiots kill people when there is a shift walk or crouch walk command, this could solve these problems.
Hey uh I know this is like super old (I was sorting by most upvotes), but I just wanted to chime in and say I don't think this is currently possible. The server is (as far as I'm aware) never informed when a player opens their chat window, only when they send an actual message. So regardless of pros/cons, it 99.99999% isn't happening.
