A more dj-oriented player/redactor on mobile. The ability to at least jump a set number of bars would do wonders., Mixo already seems to import beat grid/bpm info and i like my (hot)cues quantized to the beat.

I can't be sure that I not have glanced over something in the iOS app, but I do not recall seeing anything like that.

*possible bug territory below*

While you can add hotcues, previously added (through rekordbox in my case) memory cues do not appear in the app -- they are completely absent in desktop app and are represented only by blue stripes in iOS app.
