Grouping items that belong together is handy. Be it a door and frame, or different versions of a model. What would be nice, is if it were possible to check/uncheck visibility for items inside a group.

See thread 6333 as an example: Two different models (sofabed open and sofabed closed ) grouped together so they can be moved together. Only one should be visible at a time, but it does not seem possible to check/uncheck the visible boxes inside groups. (?) ok
