Intelligent playlist - Length

It would be nice if "Lenght" will be added to the intelligent playlist parameters.

It should become in handy to take a small break (toilet, phone call, drink,...) in a long set.

In my situation, I'll create various intelligent playlist defined by musical genre and with a length of >4.30 min <15min (to exclude already mixed compilations).

Thank you, Dj tAlpA
