 // * Tree Organization: GLTF contains Animations and Scenes

-// * (easy) Loop audio enable/disable
 // * (easy) Better Colorscheme
-// * (easy) Interactive buttons (hover/click)
 // * (medium) Visual errors for bad GLTFs
 // * (medium) Collapsable containers (Gltfs, Animations, Scenes, Audio Clips, Cameras)
 // * (medium) Spawn clicked scene
 // * (medium) Play clicked animation
 // * (idea) Use enum instead of markers for exclusive UI
+// * (medium) Add fonts similar to Audios based on inspect-fonts
+// * (hard) Add Dialogs (requires text box UI, saving, loading)
