I usually make mixes for friends, so I have been trying to use it to mark tracks that I think a person would like so I can then have a list of tracks to use in a mix, or a playlist on my empeg. So it would be nice if you could customize the mark track to whatever classification you might want. Example pressing the mark button then lets you scroll through a list of classifications. Also if you could then find the marked tracks easier in Emplode. I believe currently you have to sort by the Marked column or advanced search using "marked". It would just be nice to have a section called Marked, then you could sort them by classifications.
