IU

UI framework based on the Fusion/libui.cr library, with custom elements from watzon/cru.

Motivation

Currently avaliable Crystal UI frameworks are either not maintained anymore or the documentation is scarce and a single error might cause a developer to lose motivation, which is why I decided to build IU on top of the LibUI framework which is a multi-platform powerful UI toolkit.
