First of all, I love how your app is so easy to use yet one of the most flexible interior design ipad apps I've found. Thank you!
There are a couple of features I'm missing and would love to see:
1) Adjust wall thickness.
2) Roofs of different kinds.
3) A person object. I want to place a person in a room to get a better feel for the space.
Are you planning on implementing any of these things?
