When Subsonic creates a playlist on the Android app, it adds the songs in the order they're added to the list. The only way to change this order currently is to long-press to choose "Play Next" from the library browser, or to use the "Shuffle" option.
I'd like some way to easily reorder my playlist, as is common in many music player apps (such as Google Music's method of drag-and-drop, although I realize this can be difficult to implement in Android). A lot of times I add a bunch of songs I want to play, but don't decide on the order until the songs are playing. At this point, if I want to move a song up one spot, I have to
1) Wait until the song I want it to come after plays,
2) Long-press the song I want and Select "Go To Album",
3) Find the song in the browser and long-press to select "Play Next",
then 4) Long-press to remove the song from the playlist now that it appears twice.
This is a pain to do to rearrange songs, especially when I'm getting a slower response from my server, causing the "Connecting to server" message to appear for a long time after step (2). It would be a great improvement to be able to reorder a playlist on the fly with the Subsonic Android app. Honestly, this is the one feature missing that prevents me from using Subsonic as a complete music player replacement on my phone.
