Great app, but some issues

Great app. Work properly on iPhone 6+. Fast, smooth, no crashes.
But I have some issues.
1) Please add underground, second level and roof (roof floor) for house projects.
2) objects elevation (I cant place dishwasher on the table, for example).
3) please add parameters for doors and windows (window height is not adjustable).
4) please add sub-leveling, I mean floor in the room and different floor height in the other room (+15cm, for example)
5) please add measure tool, or a ruler tool.
