InfoScreens able to not be 100% size?

Hello, it is hard to find a good overlay like info scfreens. I like though it gives me an option for people to see rules and a modded map image. I am curious though since it looks to be stretching the UI to 100 percent is it possible to change that to like 80 percent?

Also are there any config samples for text use in it?

Thanks so much!!!! Excited to put this back in my server if we can make those changes.

Changed Status from Pending to No Response

This was my first hurdle as well. I was hoping to change it so that the menu isn't full screen. 

1. because I was using another plugin and already had images that I worked hard on
2. I'm concerned what it will look like on other people's screens. I'll have to make my images extremely large to ensure it's not stretched on someone else's screen.
