There are many windows that would benefit from having the maximize button available but don’t. I produced snapshots of the history window, the ’Downloading Package Information’ window and the ’Mark additional required changes’ window. IIRC, the downloading packages and installing packages windows are also affected, though I couldn’t produce snapshots of those right now without installing sh… numerous packages I don’t want. Software sources is also affected, I guess that should be marked separately.

All these windows tend to have huge listings in them, and scrolling through those listings in cramped space is difficult. They’re already resizable (as they should be), so why not allow easy maximizing as well?
