Currently, the program window can not be resized other than by maximizing and minimizing or using Windows built-in snapping features using the Windows key + arrow keys.

It should be able to resize freely as a normal program, as long as it is not bigger than the screen size.

When using the maximize window button the window gets too big. If you are using two monitors, you will have the remaining parts on the other screen, otherwise, you might miss some content.

This has something to do WindowStyle="None" not calculating correctly in fullscreen.

The current version can only Windows built-in snapping using the Windows key to somewhat move the program.

Preferably the menu bar or sidebar should be used for dragging the window around.
