Please make adding song to playlist and play by double click in the search area. And I miss seek bar.

For adding song to the playlist with dublclick, If I understand correctly:

- Double click a song in the search results will add it to the playlist and start playing it automaticly If that's correct - that will be added without any problems

- About the seek bar - the songs are played directly - without downloading, so seek bar is somethink that I'm not sure that I will be able to add at this point. But I will try my best to add it.

The option with double-click adding a song from the results to the playlist and automatically playing the last added song was added in 4e2a1230b341

The seek bar will wait, so I'll put the issue on hold
