Suggestion #2: Option to insert/remove/move components on 3D view

Problem description:
--------------------
- Actually you can do it on 2D view.

- But if you have some elements on the same xy plane with different z values (like shelves and some furnitures on a kitchen) you will have to show/hide elements to work on that site (to insert/remove/move/modify elements there).

- Also, modifying elements on 3D would be better to visualize modifications...

- Not splitting screen with 2D view when designing would be nice.

Suggestion:
-----------
- Add the possibility to do it on 3D view, like Google Sketchup.

- When elements snap a plane or other elements, it would become brighter to help moving elements.

- An icon on 3D view (like a pencil) would enable/disable that feature.
