Looking for a "Vendor Filter" Addon

Hello all! First post here. Now, for a while now I've been looking for an addon which does a very specific thing. What is this thing, you may ask? Well, I'd like it to "red out" or otherwise filter out any items on a vendor screen which aren't of my class's armour type. For example, as I play a warrior, any armour on the vendor menu which isn't plate would appear as if I couldn't equip it. Any hope of an addon like this coming to my attention anytime soon?
