- Add summary information to the title once the file is parsed rather than
printing it to the terminal. Now only parse errors go to the terminal. - Speedup drawing by raising and lowering tags only once everything has been drawn. Surprisingly, it now takes a little longer to parse than it does to draw. - Parameterize the layout with X_ and Y_ defines that determine the sizes of various things. - Remove unnecessary tags.
