This screenshot highlights the two biggest additions I coded today: the automatic generation of option pages for each effect (see the sources displayed!) and the gathering of scope data from XMMS. A small stub plugin sends the waveform and spectrum data to a UDP port on localhost, which Kaffeeklatsch picks up and passes to the effect renderers. Kludges rock.
If I didn't mention it, this project will be released under the GPL. At least when I decide it's not too embarrasing to release.
