I second this. Coming from VirtualDJ this is something that I genuinely miss.
Beat jump before the beginning of the song
I just came from Traktor and find it very difficult to beat jump in rekordbox. Whenever I try to beat jump before the beginning of the song (to set up the first beat of the song to hit in-phrase), it stops it at the first beat, usually throwing the track out of phrase. Traktor allows you to beat jump into silence before the first beat to properly set up the phrase in-sync. This makes it very difficult to play radio friendly songs without intros. I've used Serato before and know it also lets you beat jump into silence.
