In my humble opinion, chatzilla is both the best and the worst IRC client in the known universe. Its worst because it isn't KDE integrated like konversation is (or at least aims to be ;) ), and its the best because it uses HTML for its display. So changing the layout and colors and such is as simple as changing a HTML template, and a CSS file. It also has the ability to download the HTML and CSS files from an external website, so it allows for easy sharing of designs. As you can see in the screenshot [1], each line someone says becomes a row. If each subsequent line recieved comes from them, then another row is added to the row with their nickname in it. To get it to look like that, with the rounded edges (a mozilla-only thing), and with the avatars in the background, I use this [2] css file. It just uses their avatar (from a forum I frequent) as the background for the cell that contains their name.

Now, it kinda seems a bit unrealistic and awkward to use HTML and CSS to style this, with that wish floating around for avatars pulled from kaddressbook. So, why not do the same thing as what kopete does, with the themes and all?

Note: My main motivation behind this whole 'avatars in the irc view' thing, is that after using avatars in chatzilla, I find it many many many more times inefficient at determining who is who by simply their name alone, and the avatars give the people a 'face' instead of just a name.
