Great work there! I would like to suggest something though - File Open
Rules. So, if you click "Open" many times on a given file type
(torrents, etcetera), it will know that you want that file to be
opened. And also this should have a separate pop-up window under
Wrench - Settings - Under the hood, like the Proxy and Cache settings
have, where people can add or remove rules. These rules should be
Always open, Always download, or Always ask. I hope I was clear :D
Oh and also a bug with torrents - it does not keep the files long
enough to be loaded into any client. What about cleaning the temp
folder after closing the browser?
