Another case I've wondered about is disabling scrolling when busy dialog is up.
I see this with iPlayer add-on - the program names typically scroll, and that (probably) slows downs opening of the stream.

You can see the same if your library is on NFS (mounted locally) over wifi.
I've tried looking into it about a month ago, but unsuccessfully :|. It seems what I want is g_application.m_pPlayer.IsCaching() (or something like that, can't remember exactly), but it returns true too late (IIRC, only *after* streams have already been opened).
As it somewhat involves the player, you may have a better idea(?).
