TorrentFlux-NG is a all-in-one download application based on a web-interface. It lets you download from various protocols:
[*]HTTP[/*]
[*]FTP[/*]
[*]NZB[/*]
[*]Torrent[/*]
It can be installed using the MySQL and Website plugin, but that doesn't play nicely with the download contents folder. I would really appreciate that someone makes it a native-plugin, with download handling.
Cheers!
