Class filter in Professions?

xenolith666

I was wondering if it would be feasible that a 'by class' filter could be added to the professions? For example, I have a GWF and am leveling up mailsmithing, as well as, my TR and leatherworking. Would it be possible to add a class filter so I only have to look at the items I can actually use? Instead of everything I can't use and don't really care about? Just a convenience really, be easier to manage that way. Thanks
