The game I'm playing is a PC port of a mobile game, so I can play it in a small window. But, when the game is small, the window of this plugin becomes cannot change size.

Also, the first time I call the screen of this plugin after starting the game, it always sticks out of the window. It is more convenient if it does not stick out.

Thanks to this plugin, I don't have to create a setting screen for my mod. appreciate!
