hehehe *evil cackle*
Oh, you'll be busy for a while yet.

Okay -- I made a directory of types of plots to do in
canvas/TODO-plots

Enjoy!

agreed.
one concern -- you might want to look at m9a's Microscope function
just to make sure that there are no problems with plotting over very
very small domains (like, sine over -1*10^-50, 1*10^-50).
