DC++ should give to files nearly finished to dl a higher priority than others files.
by example : you've got 100 files in dl queue and this features gives high priority to the 25 first ones,normal to the 25 following,low to the 25 following and lowest to the 25 last files (highest is for queue lists).
that would improve the way DC++ download files (and i think will optimize usage of the temp download folder)
