Anyways, I would like to suggest an option to show all loot my class can get with spec icons next to spec-specific loot. Maybe even checkboxes in the options to hide/show loot only that spec can get.
For example, I'm a paladin. Showing all loot would have a list with, say, a healing trinket with a holy icon and a plate waist with all three icons on it. If I were to uncheck holy in the options, that waist will be the only one showing with prot and ret icons on it.
