MemesBASUIExtender is a unique mod that makes it possible to have the user interface of MemesBASUIMod in the game world, allowing you to easily access and interact with the game without having to create and attach a separate UI to the object.

You don't need to create a new UI, it's already there, it's just a matter of setting it up. All the stuff, such as sliders, buttons, etc will show up on your screen, you can drag them and use them just like you would use a map, etc.
