Sometimes I enable the bandwidth limiter to speed up other Internet enabled applications, but often forget to disable the limiter after that.
Just like the tray icon changes when we pause KTorrent, it would be nice if it also changes when the bandwith limiter is on. I believe different icon overlays (like the pause sign when it's paused) could be used for download and upload, so that one can distinguish when the limiters are on or not.
This is not a must, but I believe it would improve user experience overall.

Maybe allowing the user to set some timeout when he turns on the bandwidth limiter, so that it automatically disables, would be nice too. Other triggers could be applied like 'turn off when application XX closes', or 'when application XX stops using the bandwidth' could be useful, but I believe a timeout would suffice.

Thanks and congratulations for this awesome bittorrent client.
