Hi there, sorry to bother! This plugin is really great, but got a couple things I wanted to ask if that’s alright?

1. I’m trying to have a ‘Quest’ option in the menu - I’m also using the VisuMZ Quest System plug-in - how would I go about getting the quest journal to be opened up? 

2. Is there any way to stop the player - and others - from moving while the menu is up?

To get a custom scene opened up, simply call the scene using the method provided by the plugin you're using. Since it's VisuStella plugin, you might want to check their plugin description or ask Visu directly to know how to call their scene.

To make player not moving around, you can use Autorun method, a traditional RPG Maker feature that stop all movement on map. The second way is use Pause Events command from Pictures UI Creator. Make sure you use the latest version, which is 1.3.8
