I know that addons are available which set up their own stat displays on the character screen, for example, tankpoints has it's own display. Are there other mods that will customize what the 6 stats are that are shown there? Maybe one has already been written, if not, I imagine it shouldn't be too hard to figure out, although I've never tried to write my own mod.

The reason I want this is because I'm a feral tank, and so I like to use the defenses tab; but it has wasted slots for parry/shield block. I'd much rather put something like crit % there. It may not be strictly tanking, but it would be useful for overall gear comparisons to see how my threat/rage generation will go. If I put stamina/agility there, I may even not need to have base stats in the other window.

Similar changes could go on the melee tab, I don't need to know my weapon skill or attack rate as a cat, since neither can ever be changed. I'd prefer something that I could modify myself, but a pre-determined addon would work also. Has anything like this already been done?
