Hi, thanks for your suggestion.
Well, I'm uncertain whether I can include such a feature in my code. You would probably be better off adding another plugin that overrides what this plugin is doing. This plugin can have any name and needs to be put below the customizer plugin.
This is the code, assuming you are using MZ.
Scene_Menu.prototype.statusWindowRect = function() {
return new Rectangle(
0, // x value
0, // y value
400 * $gameParty.members().length, // replace 400 with any number
Graphics.boxHeight - 50, // height
);
}
