I am a web developer with a few ideas for the Web Interface plugin. How do I get started with replacing the current GUI?

If you download the source code you can find all the skins in plugins/webinterface/www, these files are installed in
/usr/share/kde4/apps/ktorrent/www/

KTorrent will automatically find new skins if you create a subdirectory there. Two files are required per skin: interface.html and login.html.

The webinterface works using javascript, ktorrent offers several special url's which return XML data, which is then interpreted by javascript.

Thank you so much for the post.
