I play with a ton of mods that adds many items and everything I store on the network, kinda sorta resembling a RTS style of play. So the item list clogs up the screen, if it could be sent into a window that we could open with a button, like I or Shift+L or whatever that would clean up the screen.
Maybe you could display items on screen but ones that are trackable, like add a tracking option on the new window to track items on screen.
