I understand. Sorry, I did not realize that. It's probably the reason why Sketchup has two separate entities groups and layers. Collections in Blender are more likely layers. So maybe it would be also a way to introduce something like groups, it will be just a different icon in the outliner. It's currently supported for linked objects from external sources (the package icon), which behaves like one object and has also its own origin point. But it is not possible to do it easily inside of your own scene. It is possible to use a parent object, but then I need to remember which one is the top one and which one I should move and it is sometimes hard for complex objects. It's designed for animations, not for groups.

I really like Blender, but this working with large scenes is still quite complicated, compared to Sketchup for example. I think that it is quite common to have one complex object on the scene, like TV or bed which should be handled as one object most of the time, but I still want to have the possibility to edit each sub-object separately.
