Here is a idea....

Create an option in settings to disable the ability to click on a player while running a map. (You all know what I'm talking about).
Your running a map, the chaos begins and suddenly you accidently click on a player instead of your skill or pot button and you send the infamous 1 letter private message to the player OR send a trade request. I hate that, lol.
You can still click on the players name on the upper left to send a message or invite/trade so having the ability to turn this off would be awesome!

Send a shout out if this bugs you too!
