Here are some ideas:

- java webstart support -> everybody runs the latest limewire version. This also means no more spyware but I don't install spyware anyway.

- installer should not ignore jdk1.4.0 -> scroll wheelsupport! The java only version runs fine (a bit faster even) on it.

- resume menuitem on canceled downloads

- extended info on downloads (like gnucleus)

- find more hosts option on downloads (should be executed automatically at regular intervals, this is what made morpheus so reliable)

- search refine (like gnucleus), prevents multiple queries

- a browse host option that works. Probably this requires some protocol changes/additions but it should be easy to add.

- meta information search, my favorite feature in morpheus was "find more of the same album".

- combine the latter feature with cddb (or free equivalent) to search entire albums. I now do this manually but I would love to just tell limewire to go and fetch an album, have it download the tracklist from cdbb and automatically search for each track and correcting the metainformation in the end (based on the cddb query).
