Right now on the Par tab, it just displays the par sets using the filenames. As lots of filenames can be rather cryptic or nondescript I tend to stare at par sets like "tr.par2" or "dvl-pb.par2" and think "Ok, now what had that filename again?". It'd be much easier to identify par sets if the collection group was labelled with the download folder name like it is in the download queue.
