Many thanks for this, it is looking like a much better menu implementation than what Nokia has offered so far.

However, many of my apps aren't getting categorised. Xournal, Conky, the emulators, Panucci, and others only appear in the 'All' category. I tried reinstalling Conky and now it does appear in the correct place, but I really don't want to reinstall everything. Any idea what might be wrong?
