Hold space to open Asset Browser (like UE5's Content Browser)

Description: Pressing/Holding space (or some other key) opens Asset Browser (full screen)

Reasons:
1. Screen real estate. Similar to the fantastic right-click context menu for brush properties, it saves so much space and only shows panels when artists need them.

2. Similarly, the asset browser has such little space to work with (unless you undock and expand it on another window). Icons are either too small to comprehend or they're big enough to be readable but you have to incessantly scroll.

Having a temporary asset-browser that can take up more of the screen would help with both.
