If you could make a plugin picker that integrates the preset library of each plugin, that would be nice. There's a tool that already does that by Bigtick . Perhaps that's worth pushing for integration in to Reaper. I'm all for getting to my sounds and processors quicker. So far I'm using the filter in Reapers FX browser which is just crazy fast for finding processors. Whatever the FL plugin picker does right, maybe we can mooch ideas from it that improve what Reaper already does, or takes it to the next level. Keep in mind that you want to destroy as little existing functionality as possible, but don't be afraid to push a bit. I do that all the time and it pays off.
