Show/hide walls

[Folini]

Hide, sometimes walls are cluttering my floor. I would like to flag some walls as invisible.
Same for other furnitures, so all objects could be added to the forniture panel so that I can flag as visible or not.
It would be great if those walls could be added to a group so that they could be shown/hided together.

[Puybaret]

You could make walls half transparent, reduce their height or add them to a separate level at same elevation that you could hide or not. See also this tip.
