Looks very nice! We'd love to have smarter layout systems as we
create a lot of plots for people (i.e. standard scripts that people
run instead of edit) and it's difficult to apply nice layouts that
work for every case that comes up.
Can any of this be extended to make the auto-ticking algorithms smart
enough to not overlap tick mark text fields so much? We get this all
the time with date plots and it drives people nuts.
