New Hotbar assignment fails when Mining

The new hotbar assignment in 0.8.0 build 5 to select a new Slot doesn't work well for me. The old system would add the Item to "Slot 1" and move all the others over to the right.

Can a slot just go Empty if the tool breaks or the Stack runs out so it matches this new Hotbar Assignment?

I just tested Minecraft PC version and when my pickaxe broke and Slot 1 just went empty - none of my other Slot Items moved.

Now in MCPE 0.8.0 if I have it all setup with Pickaxe 1, Shovel 2, Torch 3, etc and my pickaxe breaks I can't just select another Pickaxe and have it push all the other items to their previously assigned slots.

I have to reset every slot 1 through 6 now every time my Pickaxe or Shovel breaks.
