multi downloading/upload threads(like leech ftp)
where you have a queue coming to/from 1 site and you say choose 3 logins and it will connect to site 3 times from 1 window and say start getting file 1/2/3 then move to 4/5/6 etc
editing queue while downloading(works from above feature)
allows remote queue additions since you can change dirs as you download and add more files from different directories as u wish
multi file getter(i only seen this done once and i forgot what program does this)
say you got a 500 meg file and you chose 5 logins to download it
each login would download its own 5 parts(im not sure how this is done) and when all downloads done it will rebuild the file into big 1(probably best to use some crc software to authenticate remerger)
