Return focus after closing the pop-up window

[ovgamesdev]

key combination -> open pop-up window

When the key combination is pressed, the EarTrumpet application receives focus, but when pressed again, focus does not return to the window.

Here is an example of the requested feature using another application as an example.

Thanks @ovgamesdev. Right now, we only return focus (to the notification area) if we open the flyout via keyboard. We can handle the hotkey separately and return it to the previous window. Will try to get that in today.
