This mod doesn't add any new GUIs or anything to the game but it makes building GUIs for mods much easier with a large set of tools and functionality not found in the vanilla classes.

Features include:

Multiple Panels
Grids
Lists
Draggable camera
- allows you to move player perspective while in GUIs
Unicode and vanilla font support
and more!

buttons, lists, labels

With Panels GUIs can have multiple layers that scale with window size

toggles and buttons

Panels are also draggable so you can utilize space and can be toggled visible. When they are not visible their components are not interactable so you don't have to worry about unexpected actions from invisible buttons.

The background gui is not a panel and is therefore always interactive so long as its components are not behind another object. That way if a panel is over a button if you click on the panel the background button will not fire accidentally.

Grids and Panels together

Grids are dynamic. You only need to tell it how big you want the panels and give it a list of elements and it will automatically lay them out to best utilize the size of the grid. Once a grid has surpassed the total size a scroll bar will allow you to scroll to other entries.
