Can we put a saved search into a folder, like a normal sub-folder? If not, would it be possible/feasible to implement? It would really help keep my projects organized--I cite iTunes as support, which added the feature sometime relatively recently. Most of my folders would be better as saved searches, but I wouldn't be able to find anything if they were hanging out loose at the bottom of the library pane. Thank you!

ps: I like the new colored library pane, but on my Mac, the grey expansion arrows no longer stand out clearly against the grey-blue selection cursor.
