It'd be very handy to be able to click an 'add sweeper' button on songs in the queue, and for the system to then automatically add a sweeper to the beginning of that track. Presumably it'd be rules-based, so it'd only take files marked as sweepers, and whose length is less than the set intro time of the track it'll be sweeping. This would save a huge amount of time in having to go to the track listings, select the Sweepers folder, then sort by intro time, then check the intro length of the upcoming track, then drag a suitable sweeper across. If this is already possible and I'm missing it, please do let me know.
