Request: Inventory view button

'twould be grand if we could get a button/switch/slider on the "inventory" panel to switch views {single / multiple / all} without having to go into a separate menu....

Like: expand inventory, move items around, compress back to one pane and close....

Thank you in advance for your consideration and implementation of this wonderful idea....
:p

This is one of those things that would be fine, but I wouldn't want it prioritized over anything else. Do it if there's nothing else in the queue left to do, but don't spend time on this when that time could be spent on other things.
