Option to disable permanent notifications

It would be great if the permanent notification with the speeds in the bar could be turned off so that it works only show a message when a download finishes. Some context:

The android client I'm using this on is hooked up to my TV and continuesly shows pop-ups for each new notification. For ttorrent this means I set one pop-up per second each time the download / upload speed changes,which is very annoying.
