The Anaconda window I get when I install to hard drive from the Fedora 7 LiveCD is not resizeable like other windows. If this would not cause other problems, it would be more consistent with other windows if it were able to be resized. In particular, it would be convenient to maximize it to fill the whole screen. (At the resolution my laptop uses, it's in a large but not maximized window.)
The artwork and UI in anaconda is not designed to run at different resolutions, making this a pretty large amount of work to do.
