Hey there.
If I'm being honest, I don't know as much about windows and menus as I probably should, and a peak into the code will probably reveal that to anyone who knows what to look for.
That being said, the windows I create in this plugin are bog standard in pretty much every respect, so whatever you did to the menu to hide the background, border and blur should also work just fine in the crafting scene. If that was a plugin designed to do that to multiple menus, it should be as easy as adding my window names, scene_craft to that plugin to enable it.
Depending on how the plugin was made, it might already do that to all scenes and windows, so maybe it would already work with my plugin, too, assuming you haven't already tried it, anyway.
If it was something more custom that you did yourself, you should be able to modify those windows in the same way you did in the main menu.
There isn't anything in this plugin that should be a problem if you were to do that, anyways.
