Feature description:
In the Queue view, add a way to “play next” for songs instead of having to drag them up, scroll, drag, scrol, etc…
Maybe re-use the long-press & drag used to add songs from other views to the queue (which I only discovered while loooking for duplicates of this feature request)
Problem solved:
Re-organizing a queue can be painfully frustrating at times. Specific example:
Getting songs that are far down in the queue and bringing them up to be next to be played
Brought benefits:
Less scrolling and shuffling around, more getting to the good stuff 
I believe this would make quick re-organizing a queue (especially a shuffled one) more enjoyable
Other application solutions:
The previous app I was using, Musicolet, gave advanced queue organisation tools that allowed for quicker re-ordering. I was mostly using play next, which seems like the most important from my POV
Additional description and context:
Digging a bit into my routine and why this makes sense. I usually queue my full favorite list so that I don’t have to think too hard about what to listen to when going to work, shopping, etc… but I often still go and do a bit of reordering to make sure I’m happy with whatever coming up next (Yes, I’m a pain)
That is made harder by Symfonium not giving me an easy way to “play next” for songs in the queue. the further down I go, the harder it gets.
Screenshots / Mockup:
Sorry, no mockup here. But since this behavior exists elsewhere in the app (which I’m unable to screenshot) I hope this would not be too hard.
PS: Great app and incredible dedication to your user base
