Slide extra Mac windows off the screen and bring them back

Stash one side of the desk, hide everything but the window you are using, or cycle through what you tucked away.

Minimizing a window hides it in the Dock, which is a poor place to remember why you hid it. Stash slides the window off the screen and keeps it easy to bring back.

Stash what is in the way

Stash one side when that half of the display is the clutter.
Stash everything but the window you are using when you need a clear screen for a minute.
Cycle through what you hid when you want a specific window back and you do not want the whole pile at once.

The window is off-screen, not closed. Bring it back when the reference or the message matters again.

Use a different action for a different problem

If the window should occupy half the screen, throw it or snap it. If it should stay visible on top of the others, that is a pin in Shoverlay for an image, or Pin Mode in Gablet for a live window. Stash is specifically for getting a window out of sight without losing it.
