"Switch between open Windows" integration into "All Apps"

Description of the new feature / enhancement

Hi,

Switching between open Windows (< = “Switch between open Windows) should be integrated into the all Apps search (“All Apps”). To show if an App has already an open Window.

Scenario when this would be used?

When I use "Command Palette" I do not check my taskbars to see if a program already has open windows, so I will not use the prefix.

Conversely, if I already have to check my taskbars to see if a program has an open window, I won't use "Command Palette" because I already have my mice in hand

Supporting information

My preferred method would be to display all open windows for an app directly when searching in “All Apps” and only secondly an option to open a new window for the searched app.

For a better overview, it would also be possible to display a note "Has open windows" for the searched app, which I can then display with a key combination (for example "Shift+Enter or "Ctrl+Enter").
