Unable to use it with window_manager.

The code for hiding windows at startup in the window_manager plugin conflicts with the code that needs to be modified for this plugin. You can find more information about the hidden-at-launch feature in the window_manager#hidden-at-launch section.

@jpnurmi re-implemented window manager in yaru_window which is also used in yaru_widgets I recommend to use those, they work perfectly fine with handy window

[wilinz]

This library currently cannot replace all the functionalities of a window manager, such as adjusting window positions and so on.
