I missed several hotkeys I'd expected
  1. close\collapse bottom panel (ctrl + ~ in VsCode)
  2. turn on\off zen mode. In zen mode main (middle) panel is in focus, other panels collapsed or hidden
  3. format code (alt + shift + f in VsCode)
  4. a button to open\collapse left sidebar or a button per each piece of it (components, app structure, pages, etc)
I'd expect to see those combinations in tooltips for those buttons, it would make it easy to learn
Maybe other users have more suggestions for hot keys
