HI there! This plugin is AWESOME! Thank you for porting it over to MZ. Quick question (my Javascript knowledge is low). I am using Visustella Main Menu/Core plugins (as well as a larger resolution than standard) and my window looks like this (uncentered). Any advice on what I could do? Thank you :)

Just played around with that myself. Changing the resolution to 1280x720 for main window and UI fixes this for me.

Edit: Yes, I did make sure to use the main menu plugin you were using. 

Edit Edit: Just tested it with the UI resolution by default, and I am 99% certain you have the UI resolution not equal to your Screen resolution, since the same exact thing you have in your screenshot is what happens when I keep the UI resolution smaller than the screen.
