As a followup, my terminal windows are rarely the same size as my browser windows. I don't like resizing my browser windows in general because the browser will remember the new size, even though it was meant as a once-off window. So having a browser-sized terminal doesn't seem like a very good experience.

Additionally, it doesn't even work right. In a screen-controlling app like vim it seems fine, but in the normal shell, once I enter enough text to use more than a screen, the bottom-most line is actually off the window (even if I scroll down).
