Most digital comics are downloaded through BitTorrent. It would be very cool to be able to search for a book on the major trackers, and initiate a download, straight from Comix. This could be done by:
1) implementing an OpenSearch-compatible search box, so that you can reuse straight away all the search plugins for Firefox which most trackers already provide.
2) on hitting "return" in the search box, Comix should either open an embedded or external browser with the result of the search query.
I do work with Python, but I'm not familiar with PyGTK. How hard would it be to add the required GUI elements (a search box and a tab in Preferences to manage the plugins)? If you can give me a pointer, I could probably come up with a patch.
