Note this feedback comes from discussions with over 200 DJ's I have interacted with over the last 15 years using Traktor
Idea: A button in the row for each track in the browser which you can click to mark that you want to play that track later
Usecase: Allowing you to mark which tracks you want to play later
Description: while browsing tracks in Traktor I sometimes come across another song that I want to play but just not right now, having a button in the track row you can click to mark you want to play it later would be very useful
