The Blender Inventory

If you have used 2.80 you may have noticed 1-2-3 ... keys no longer swaps between Layers. Since we now have Collections. On a side note I noticed the same behavior in Texture Paint/ Sculpt -mode also. There was no fast way to organize my brushes and to swap between them with 1 .. 2 .. 3 key etcetera.

Now I have my own Pie Menu for brushes so it's not that disruptive for my work flow speed. But it's in my bone marrow to press 1 .. 2 ... 3 keys for my favorite brushes. If you can relate to this, hear me out.

How about a Blender 'inventory' that floats in bottom-center of view? So For each modes, like Object, Texture Paint and Sculpt you have a customizable inventory you can add your favorite tools to and swap between them quickly with the number keys?

For me this would be incredible to have in Sculpt and Texture Paint mode which I've done a quick mock-up.

What do you think?
