Like what SkyOS is doing at the moment and where it's going? then you would like to know that it's already possible to do some gui desings in SkyOS, for this purpose there is a wiki page site online now.

The purpose of the wiki is to act as staging ground for short term fixes, as well as long term fundamental changes to the graphical user interface (GUI) for SkyOS. This website acts like a specification for suggested and upcoming minor GUI changes.

Since build 6795 of SkyOS, it has been possible to customize various aspects of the WindUI parameters by use of the DataCollectionEditor.
