I just wish that most of these browsers gave me more customizability. I want more vertical real estate available, but I have plenty of horizontal space because screens went from 1.33:1 to 1.78:1 (or 1.6:1 in the case of my home monitor).
I'm using Opera, because it lets me do the following:
* Have tabs along the right edge of the window
* Have arbitrary, collapsible panels along the left edge of the window
* Place all remaining controls (menu button, panel toggle, nav controls, location bar, extensions, img toggle, css toggle, fit-to-width toggle, etc) in status bar
There are other elements of customisability that I really enjoy having, but I just wanted to focus on the visual stuff. Top-edge tabs just doesn't work with my crazy browsing habits of "right-click on every interesting link and gradually read them as I go along" and "reading many-page forum threads on an ongoing basis". Beyond that, it's just nice to get every crucial widget as out of the way as possible but still immediately accessible.
Just for fun, I have
uploaded a screen cap to make your eyes bleed.
I do like Chrome/Chromium, but it's only good for limited uses and to use as a crude web kiosk for guests logging into my computer.
