Minfeaturesize??

[Stephen Woodbridge]

Steve,

That would be really great to have in 4.6. I am also thinking about
adding an area attribute to my tiger2shape translator or a utility to
compute the area from a shape and add it to the attributes. But I think
having this feature makes it much friendlier for people that don't have
the attribute column to start with to get a better looking map.

Thank you for your support,
  -Steve W.
