I would like to see powerfull demo recorder + many settings for moviemaking like while watching demos we can delete HUD etc.
It will help in improving beginners skill ( demo sharing ) and will improve MovieMakers work.
Who of you wouldn't see same great movies like does CS or CoD4 community?

Demos are just better to share with community than .avi movies:
+small size
+you run it with game, you don't need any codecs
+no rendering a few GB file
+even with slower hardware your FPS won't drop
IMO. when you are dead you should see just black screen + chat. But AgentX told that already some time ago.
