but it only helps in the very specific scenario of changing the order of a playlist with 100s of tracks in it. Are there enough people doing that on a regular basis to warrant the time to implement the other methods?
Forgive me, I wouldn't consider changing tracks around a playlist any more of a "very specific scenario" than doing many other operations that MB facilitates.
The "very specific" scenario I was referring to is repositioning a track 100s of positions up or down in an existing playlist. In that case being able to type the required position might be more efficient. Otherwise, I think dragging would still be faster and easier, especially if the requested acceleration was implemented.
Bee excellent to each other...
