Add virtual button to switch screen (iPad OS)

[KitkatYeung]

I'm using my outdated iPad as a second screen (Sunshine and EDID loader: extend screen). Switching streaming screen at moonlight is impossible without a keyboard.

Is your feature request related to a problem? Please describe.
It is not a problem for iPad keyboard users. But if not using a keyboard the switch screen feature is not usable.

Describe the solution you'd like
Add a semi transparent/hide-able shortcut button with text to indicate what is the current monitor and tap this button to loop all monitors.

Describe alternatives you've considered
Connect a physical keyboard, but not always possible :>

my fork will implement a feature could potentially & partially meet what you want.
there'll be a semi-transparent on screen button (relocatable) to simulate keyboard, both single key or key combination (like ctrl+shift+esc)
you may create a shorcut on Windows desktop with shortcut key to execute anything.

Coming soon within this week
