I really would like to have access to side by side/full screen inventory panels that display an entire inventory at once for easier sorting.
Its called party pannels now ...
Its on the top of that new party ui on left side of your screen ...
Then, if you want ONLY to work with inventories, you simply expand them over your character by that tiny and easily to oversight arrow in top left corner of your screen.

If i missunderstand your problem then sory.

But i thought this could be helpfull.

Personaly i had to completely change my binds ...
Since Equipment no longer do anything (???) i use it now for character panel, all is there so quite fine.
And i use Party Pannels instead of Inventory, since that shows whole party.
