Two suggestions

#1 - A smaller detachable statistics window. Maybe something that would sit in the tray and show upload/download bandwidth, or something that could shrink down into the size of a window's top bar, so it could "hide" on top of all my windows without blocking anything important.

#2 - A better system for keeping track of the sites you visit. I'm thinking something along the lines of a bookmark system, or some other way to make the site list perminate, and assoicate settings with the individual site (passive/active mode, security settings, etc). Just something better than the drop down combo.
