I know nothing about coding, so even though it sounds simple, I hope it is also simple to make it a reality.
Basically, when you play medic, and let's say you are on the first point on Dustbowl (stage 3) (and yes, that map I released) and a buddy lf yours (Prosniper543) calls for medic at the second point. Before, it simply said that somebody was calling for medic if they were not on screen. You don't know who it is, and for all you know, it could be Player as a spy who took 1 hit point of damage. Now, (assuming a wonderful person makes this plugin) it has the team coloured name (like if you put your crosshair over a person) below the medic sign. I don't think this would be needed for fire, as I don't want to trouble anyone who wants to make this. If you do, maybe as an addition or something, I don't know.
If you think this is useless:
1) Can pair you up with a friend easier.
2) Know who is calling, and you can determine if going over to their direction is worthwhile (Orange Juice is a scout, and calls for medic which points left. TAAAAANK is a very good soldier, and the pointer points right).
3) Has the ability to regroup, like a heavy, to protect the medic, but you now know that it wasn't a sniper calling it out.
Thank you to anyone who thinks they can perform this. If for some reason, this is actually a very difficult thing to do, I don't blame you on giving up.
