Thanks for picking up the plugin! Let us know if there are any features you would like to see or if any bugs/compatibility issues pop up.
With regard to MV support, it's actually quite the opposite! MZ is an absolute pain in the arse to work with while MV is very easy to slap things together. MZ's code is a lot cleaner and better optimized but they make even simple things like resizing a window a nightmare because of the added considerations for rect formatting and multiple resolutions. The MZ Sprite classes in particular cause a lot of trouble when we port the plugins over because they are considerably different from how MV does things. MZ's method of registering plugin commands is so annoying that some devs just hack in a way for you to use them via the MV legacy method so as to not deal with the hassle (MZ3D does this iirc).
It's not all bad though just a bunch of hoops you have to get used to jumping through :)
