In my opinion, what should the user hide in terms of chat to the server/game? We can already catch +/- all their input if they start chatting (except some characters for now) with some ‘key logging’.
And this event cannot be used by anything outside the CoreScripts or the CommandBar in Studio right now so making yet another function when this is unlocked wouldn’t be needed in my opinion. Unlocking this would help people a lot for making custom Chat GUIs without the need to remake the ChatBar. (Making a so called ‘key logger’ to detect teamchat is not possible right now due the already mentioned issue above)
