What does the "Counter" option do?
Encounters->Lich King -> Defile Cooldown -> next to "Flash Screen" is the option to enable "Counter" and no matter what i pick, enable or disable, the test seems to be the same.
@kunda: the default can be show all icons, and experienced users can toggle some marks off when they want. Anub25hc is a very good scenario of how useful this can be:
Most guilds heal Penetrating Cold (PC) either by assigning a number to each healer, and each healer counts the PCs (from frame 1 to frame25 assuming all healers see the same grid layout).
What other guilds use, is an addon to put raid marks on PC targets and each healer heals some specific raid marked person. However finding your mark from all the symbols that suddenly pop up on your grid takes a little time during which people might die. With raid icon filtering, it will be a trivally easy task to quickly pick your correct heal target.
Request for: GridStatusRaidIcons
Change: allow user to select which raid icons will be shown and which hidden (For example, show MOON and CROSS on grid, but don't show SKULL).
Will be useful on Anub25hc.
Will settle for a quick and dirty configuration inside the LAU code.
