Hi, I'm a djay and I check many playlist a week. Most playlist didn't show the current date, but only the time/date of it's refreshments and I can't remember all that already checked songs. Only way to mark outsorted songs is to save them to favorites, but that's not really a pratical solution. To avoid hearing a lot of outsorted or already accepted songs again and again it would be nice to have an additional checkbox for every song. That would make it much easier and would save a lot of time.
