I recall someone saying this over on the planetwolfenstein forums and I thought it was a pretty good idea. Anyway his beef was that whenever you heard a teamchat or vsay_team and got the coordinates from their message, it was hard to tell where they were unless you opened up the trans map and searched for it.
He proposed to put the coordinates directly onto the automap, giving the player a better sense of where he is and his teammates are on the battlefield. Then whenever someone gives a team message or is on the same fireteam as you, you will be able to derive a general location of your comrade.
I’m implementing it into my map and I just thought I’d pass it on and see what you guys think.
