qtools-ui
This is a collection of useful widgets and pre-made components for use in your Qt applications. There is no specific scope that limits what might fit into this library, but for the most part it concerns itself with things like layouting and other base components that can be used anywhere.

The project can be found on github including a fully documented symbol index.
As of November 2015, Qtools-UI is on Quicklisp.
