SC2 cannot be played on 21:9 RESOLUTION - please add

Blizzard please add 21:9 resolution to SC2, because currently its unplayable on 21:9 monitors as far as i can tell, if you go into fullscreen you will have to get used to all your other windows constantly being wierd every time you tab in/out of the game. If you go fullscreen windowed you cant scroll down because there is a task bar thingy. Please just add 21:9 to make it available for 21:9 monitors, if your worried about 21:9 having and advantage then dont allow it above some high rating or at pro level or something.
