I know that the devs already thought about this, I’m mostly posting this in the event that their idea of thrall storage is limited simply to the ones you have yet to place into a wheel of pain.
What I’m saying here, is that the ability to place un-trained thralls in cages is, in my honest opinion a must, but further then that, it would also be a good idea to have ways of “storing” tamed ones. Assigning them to beds or placing those you don’t like in cages too. Things that would allow to stack them close to each other so you can keep them out of the way when you don’t need them. Makes more sense then stuffing them in a box. XD
Also, would be helpful in reducing the clutter when you have several combat thralls spawned. If not this, then please at least let us pick them up and toss them back into a box.
