Feature request: option to group windows per app instance when using the "window" switcher mode

[josser900]

This is a great alternative to the Window 11 Alt-tab.
I'm using several apps that have multiple windows, some seem to be invisible (but the pre-release version does not seem to fix it, so maybe not really invisible) and other apps are MDI applications (with 2-5 child windows). When running multiple instances of these apps, it's difficult to switch between them in the "app" switch mode. And in the "window" mode you get a lot of windows and it's difficult to find the right app instance.
Is it possible to add an option to the "window" switch mode that groups all windows per app instance?

Or maybe it makes more sense to have an option for the switcher mode "app" to not group apps but show all separate app instances.
