@Spikard - You lost me. Let's say I want to cast heal on the character currently in the "F1" position... Are you saying that I can click the heal spell, then click F1?
My point was that sometimes it is difficult to target a melee character surrounded by 3 or 4 mobs. I often spend (read: waste) time adjusting the camera, rotating, zooming, etc., just to be able to target my melee guy. Being able to target the portraits seems like a simple solution.
@Endre - Spot on. I really enjoy the game, and I just want it to be as good as it can be. Cheers.
