As per popular demand we have added zen mode to vscode. Verify:

• Going in and out of zen mode is a smooth process (view menu, command palette, keybinding)
• Zen mode hides all workbench parts and goes into full screen
• You are still able to open workbench parts (sidebar, panel...) in zen mode
• Going out of full screen while in zen mode takes you out of zen mode
• Setting workbench.fullScreenZenMode is respected

Sweet ! Looking forward to this feature 👍

@jochenvw you can use the insiders build as it has it right now (though shortcut key is going to be changed in the tomorrow's build)

@isidorn Excellent - I'm a preview user now :)

@bgashler1 I know you tested this item but not sure if you finished -> if yes just check off your checkbox here so we can close this test item.

✅ just found one little issue that may be by design (above).
