I hope with 4.0 serato also upgraded the video screen we need more video transitions virttual dj also uses 4 deck video mixing serato is way behind on this like light years serato is old tech and needs a big overhaul virtual dj has more ways to display the playing video next to the other deck im thinking of switching until serato catches up to other dj software rekordbox is way behind as well which sucks for us video djs come on serato catch up
