I found this plugin helpful for having a "Gallery" command in the Title menu after certain conditions were met. But I noticed a problem with the Options settings not being loaded when starting the game in MV. This change around line 522 fixed it:
ConfigManager.applyData = function(config) {
//BUGFIX: call the original to get the other stuff
ConfigManager_applyData.call(this, config);
this.newGamePlusEnabled = this.readFlag(config, 'newGamePlusEnabled', false);
//The last parameter is the default value in MZ
};
