Well, any way of letting users customize what they don't want seen? As I mentioned, I love the function, always handy to see what other of my characters have some material I need for that Engineering or Blacksmithing thingy I'm working on, but seeing that nine others of my characters have a Hearthstone... it doesn't really help much.
Just a little window to write names of items that the Warehouse doesn't list, that's all I ask.
