When we hover the mouse cursor over the Maximise button, it fails to show us the standard Snap Layouts, preventing us from quickly, easily snapping the window to the desired portion of the screen.
This is also a bigger issue if we need to snap it to one of the positions which isn't the basic half, or quadrants.
Yes, there are workarounds, using the win-key shortcuts, like Win + Z, or Win + -> or drag the app with the mouse.
But PMPC should just work with the standard behaviour. Which all its users are familiar with.
