add Imperial units as an option. i.e. Feet and Inches.
Not everyone in the world uses metric. (even though they probably should) The world I live in is more easily measured in feet and inches.
You find the option in the menue "Properties - Units"
I had trouble with this at first as well, but soon discovered that you can change everything to Imperial units if you'd like. In the Roomle interface roll over the "Properties" menu and click the "Unit" option. In the window that pops up you can choose between "cm" and "inch".
This really is critical for those of us in the US to effectively use Roomle. I have no idea what my room dimensions are in centimeters and it takes me a long time to do the unit conversion. Please give us support for using feet and inches!
