You've come to the right place, I'm about to pimp your µTorrent!
All you have to do is make sure that µTorrent is running, click the 'Pimp My µTorrent' button below, grant the permission in µTorrent (a dialog will pop up) sit back and relax!
If you don't like what was done here, you can always undo the changes that Pimp My µTorrent made (but why the hell would you do that?)
If you don't like the 'pro style' side bar you can
It's Javascript Magic. A couple of years ago BitTorrent (the company that owns µTorrent) decided to experiment with bringing Torrent support to the browser using a version of µTorrent that runs without a User Interface, called Torque, and then kind of abandoned it. (frankly, it kinda sucked)
The promise it made was beautiful though, so I reverse engineered it, and took it to the next level when I found out that the protocol it talks is embedded in the µTorrent and BitTorrent clients to this day. The result is DuckieTorrent, an angular.js module that I use in DuckieTV
All that the code does on this page is connect to your µTorrent client and change the relevant hidden settings.
There is no catch, this is free and effortless because this is the way BitTorrent built their application. It's been a public secret for years that it is possible to do this. If you want to find out more, you can read about it on the µTorrent forums
