Custom tabs would be nice, kind a like chat windows, where I can tick what i'd like to see in each.

Tick boxes could cover, materials, materia, gear types (foot, head etc), gear class/job types (gld, pld, war, mdr, etc)

It sounds complicated, but it would actually be very easy to implement, doing something like this in SQL would be a synch, so hopefully the FFXIV coders could manage it in their engine.
