Here is a screenshot of Kynaptic, a new experiment I’m working on. This is a KDE-based frontend for APT-RPM and APT. Kynaptic is based on Synaptic, and shares the same base code on top of the APT library.
On the right side you see a new toy: the interactive search dialog. This should definetly improve the user experience while looking for packages, and could eventually be ported to Synaptic itself.
Another interesting point is that during the development process of Kynaptic I’m also cleaning up the Synaptic code, something I had in my mind for some time already.
