However there are many times when I want to listen to a particular song and the two search modes, append or replace, don't do what I want, which is to make the song I search for become the current song in my playlist, without disrupting the rest of the playlist.

I believe there is an "insert" mode in 1.1

I would love it if I could navigate and select songs to append to my playlist while still remaining point in the tree that I navigated to.

These are essentially items 2 and 4 on my top 3 wishes list. I don't think they'll be in 1.1...
