a little idea for the iceblocking problem...

i hope you are using ISBoxer (or HKN) which allow mouseclicking to pass in regions.
As been posted in other topics here this method is used with addons like Grid+Clique or Healbot to pass clicks to the healer.

Add a region on your main window to pass trough over your Grid addon and use Grid-Custom Layouts to make the party order the same on each screen.
Then enable Clique addon to do Iceblock on right click.

If you see a mage getting a beating, right click on his frame in grid which passes the click to all screens enabling only that mage to iceblock.

not sure if iceblock can be used with Clique, but worth a shot.


Another option would be to use your bar addon to add small bars next to the party screens to allow iceblock to be placed, used with regions to only iceblock that one.


If all else fails, make 5 keybinds to iceblock each individually:
ie. F1 = iceblock char 1
F2 = iceblock char 2.
