Sorry, but I won't work on a status menu plugin of my own. I could to be sure but it would be kinda limited to what I would think it should be... and I don't like limiting the users that much to my own tastes. Mainly because I am aware I'm not a great visual designer.
Instead, my plan is to give you options to show on the current status screen, and add functions to make it easier to get the information you need for adding them in your own custom menus. Maybe some status screens will even already take the changes from the default one, would save the users lots of work.
Hmm, what exactly is the error? I used to use them myself, and never had any problems.
I usually put my plugins under all Yanfly ones, but to be honest I don't think it should cause a problem no matter the position it is put on. Or well, didn't until you said you got an error.
If you could show me a screenshot of the console (some projects open it with F8, others with F12, no idea why, a project I made myself always opens with F8 but some people sent me only open with F12), the default error screen doesn't give barely any info save that an erro happened. Yanfly's makes it give some extra info, but it is not as easy to read as in the console itself and there may be more relevant info the error screen doesn't show.
