Good to see this is still maintained and a new version is planned which moves away from jquery. We used to use this in a project few years back and it enabled us to quickly prototype low-effort admin interfaces. It is a nice package that provides commonly useful interface components like resizable panels, data grids, toolbars, tabs etc. which looked good out of the box. We eventually moved away because RTL support was missing, and decided to use more specialized libraries which provided more control over form validation, and a more feature-rich datagrid. But it was a pleasant getting-started experience while our team was small, and speed of iteration was more important than featureset. The author is also quite helpful.
