Feature request: searching within a playlist

[mYnDstrEAm]

One can't search within a playlist. Sometimes, I'd like to find/play a specific track within a playlist and continue the playlist afterwards.

It's really hard to use this app without this feature and it would be very useful because then you don't need to reopen the playlist after the track played (currently it only play the few search results even if the track was in the playlist).
