Hi Wayne,

   I love the idea of multiplot. Would it be possible in the future to
remove the constraints requiring rectangle or line selections (to
include ovals and freehand ROIs) and to increase the number of ROIs that
can be plotted. It seems like there is a limit of 6 ROIs that multiplot
can handle. I would often like to plot 100+.

Many thanks,
Damon
