Add an emergency radio channel that everybody has access to.

Alternatively, if using the PDA was made easier and quicker, an emergency channel wouldn't be needed.

I noticed that it's possible to carry on PDA conversations by just clicking in the chat window when you get messages.

Would it be possible to move PDA funtions to a tab on the right side of the screen rather than having it be required to use it in hand?
