hey no worries about the late reply. sorry to hear you lost all your scripts!
i actually gave up on the tree and went back to filters, it just works better for me. plus, since i started using the new playlist tree component, i have been making lots of autoplaylists which fulfills the same function.
i've been thinking of making a mini config too, but one that i can switch to after i decide what to listen to and set up a playlist.
for quick previews from my file manager i use Billy which is absolutely brilliant. it can be set to queue up all audio files in the directory it starts from, so opening a single song can pull up a whole album. it's great for listening to stuff before i have added it to my foobar library.
