Hi!
I think it could be good to see both:
- The actual PCB area of the outline (well, without drills).
- The max-width * max-height which is usually what you have to pay for when you get it manufactured.
The second one could be also an interesting task to calculate if you have an odd shaped polygonal outline.

Regards,
Clemens

For an example of this see the dialog_create_array.cpp file. This way if any new options must be added in the future, they can just be added to the struct very easily.

When translations are done, they need to examine the entire string that needs translating, so the ":" character should be included in the string. Separating out the two portions is the equivalent of saying that every lanugage will follow the same compositional rules.
