Hello Pioneer and Rekordbox DJs!!!

Working on an educational project in digital product management and have an idea for a feature within the rekordbox system that could help us all. Would love to hear your thoughts on the following questions:

Do you create studio mixes or recorded mixes to publish? How do you approach these type of mixes?

Is important to you to play unique/original tracks when you are recording mixes that you publish? Do you try to avoid repeating tracks from past recorded mixes?

If so, are you able to remember which tracks you played in past mixes?

Do you have a system or approach that is working for you to keep track of played tracks in past sessions?

Would a visual element in rekordbox or on CDJs/XDJs that indicated tracks played in past mixes, be helpful to you?

Thanks so much for your time!
