Badly thought out button mapping and broken splitting of Item Stacks in Trade Board

The button to build towers (L3) is the same one which displays ALL loot on the ground and this is a big problem.

If you do this in a beyonded map that dropped a lot of loot., you can simply freeze because you pressed L3 a little off the tower and now it shows you all the loot while your minions run around and 100 monsters stream to you.


Also, since the last patch you cannot split stacks of items anymore while in trade window.
(For example I can't take my pile of 10Chaos and split 3 Chaos off, now you always have to leave the trade board UI to do such.
