oh there are plenty such. kget, aria2, uget, and motrix off the top of my head. but people use jdownloader for the same reason they use windows -- it's what they know.
More like JDownloader supports almost every download host website in existence without any hoops. Most other applications just support standard http downloads which may be difficult to use with many websites.
Same shit different software. I'm still using that turd Filezilla because literally no other FTP software I've tried has worked with the server run by WiiU homebrew.
Yeah, there's a module for the modern custom firmware that runs an ftp server in the background for file access. Let's you manage things, add homebrew, install games, etc without constantly swapping the SD card. For whatever reason, though, GNOME commander can't connect at all and gFTP disconnects immediately when trying to make a transfer.
Does that one have something like Click'nLoad and a Browser add-on or app to allow for it when the Downloader is running on a remote machine? Can it run on my server and be accessed through a browser or said app?
Edit:
oh whoops that's totally my bad, didn't realize that what OP mentioned was a download manager just looked at the screenshot and assumed it was a torrent software from how it looked
