XChat Aqua seems almost incomplete after using XChat in Windows. The tab bar was shifted way to the right, for one thing. It was quite usable otherwise, and maybe the interface was the way the porter(s) intended it to be, I don't know. But either way, I am looking for a good tabbed-interface IRC client for MacOS X as well. Does anyone here know the Baxter IRC client from BeOS? Perhaps the best tabbed interface of all time. Something like that, for MacOS X, would be great!
For now, I'm trying out everything I can find, and maybe I'll find something with a better approach.
