Hi Matthias
LADSPA plugins are categorised using RDF files - you can usually find them under /usr/share/ladspa/rdf (or do 
$ echo $LADSPA_RDF_PATH)
in case they're installed somewhere else on your distro)
Plugins that aren't categorised lack a description in one of these files, and your best bet would be to write them up yourself. You can get away with copying the header and root element from one of the other files:
---8<---

<?xml version="1.0" encoding="ISO-8859-1"?>
]>
--->8---
and then add an entry for each plugin you want to categorise inside the root element (just before '') - you'll only need to add three lines for each plugin - e.g:
    Bandlimited Sawtooth Oscillator
The ID (1641 in the example above) and title you can get using the analyseplugin utility that comes with ladspa. The availbale categories (OscillatorPlugin etc) are found in $LADSPA_RDF_PATH/ladspa.rdfs
Hope this helps!
