New Workspace Desktop ⌃⌥⌘N
A brand-new Desktop with your default layout. Out of the box: Chrome (or Safari), Terminal and Finder at 33, 44 and 23 percent of the screen.
OpenDesktop lives in your Mac's menu bar. It opens a fresh Desktop with your browser, Terminal and Finder side by side, and puts every other Desktop back in order when things pile up.
Every command has a shortcut, so a fresh, tidy workspace is one keystroke away.

Windows piled on top of each other snap back into their columns, even with two windows of the same app.
Every Desktop at once: workspaces back in columns, everything else sorted by kind, empty Desktops gone. Three dings when it's done.
Save a Desktop exactly as it is: every app, where it sits, Chrome's tabs, Finder's folder, Terminal's directory. Reopen it on a new Desktop from a gallery of cards, and make any template the one ⌃⌥⌘N opens.
Closes every window on the Desktop and removes it, after you confirm. Anything unsaved still asks you first.
Optional: while you're away from your Mac, OpenDesktop deletes Desktops with nothing on them, so Mission Control stays short.
The tools that keep a Mac full of windows calm.
Videos with videos, images with images, chats with chats, apps with apps, on as few Desktops as hold them comfortably.
Every app and where it sits. Reopen it later on a new Desktop, on the screen it was saved from, from a gallery with a screenshot of each layout.

OpenDesktop is three small panes in your menu bar. Nothing else to learn.
Once, and then it's one keystroke.
macOS has no public way to create a Desktop, so OpenDesktop drives Mission Control the way you would.
