Kayak UI is in the very early stages of development. Important features are missing and some documentation is missing. Kayak UI is designed to only work with Bevy.

• Basic widget and global state management
• Input events (Mouse, Keyboard, Char)
• Fast and accurate layouts using morphorm: https://github.com/geom3trik/morphorm

• Image and NinePatch renderer
