Please provide an interface which could be accesible from anywhere, PC, Tablet, etc; to manage torrents, increase or decrease download speeds, set file priorities, and assign new torrents for download.
I would really like this too. There are many browser addons for Chrome/Firefox etc that let you add torrents/magnet links to remote torrent clients straight from the browser.
The only feature I really need is to be able to add torrents remotely, I don't even care about other controls.
