I'm a KTorrent user in Linux using qBittorrent on Windows 7. I've found it to be excellent thus far

Here are a few KTorrent features that I would love to see in qBittorrent:
1. Stalled torrent: When a torrent stalls with no activity for X minutes, I'd like to see it drop down the queue.
2. Pause/resume: I'd like to have an option to pause all torrents and resume them as needed. This would be coupled with a toolbar button as well as a tray icon context menu option. The tray icon would change to reflect if the app is in pause mode or resume.
3. Alternative speeds: I'm currently using the alternative speed option to "pause" qBittorrent. Regardless of point 2 above, using a different tray icon for this will be nice.
4. Allow tracker filters: Allow users to filter only the torrents that belong to a particular tracker. For examples, if I have torrents belonging to tracker1.foo.com, tracker2.foo.com, tracker.bar.com, and tracker.baz.com, it would be great to filter only the torrents belonging to foo.com at the click of a label-like category item. Similarly, bar.com, and baz.com would also be available.
Thank you all
