Hi! I believe this is not an existing feature? It would be great to have an Action that places the currently active app in the last position in the “App Switcher”, or the thing that comes up when you press Command+Tab.
This is mostly useful in combination with other actions, such as having a keyboard shortcut to execute some commands in an app, hide it, then place it out of the way.
The problems that I do see with this is that maybe this isn’t possible with any of the Apple-provided APIs and such. But it would be a great little addition if possible.
