Having an area calculator would be awesome!

could it be possible to get the area of a shape like it is possible to get the length in the "Object" tag of the information panel.
When calculating how much material to buy e.g. architecture and interior design - calculating m² of flooring/cladding/tiling required

When creating emboss dies for label printing we need to know the area of the emboss on the label as the embossing units have maximum area they can emboss in one hit. This calculation (without using a third party script) would be very useful.
This can be scripted though and this is what I use, I'd like to have it natively; in document chosen units (squared), correctly for compound paths also.
