Grouping in an empty object I can group several objects using Ctrl+P.
However, the "main" object is the last selected object.
I find this a bit distracting.
Is there a way to group my objects in an empty object?

I would like to be able to parent my objects like this:



I was not really able to do that, so I added a plane as the main-object.
Is there a way to do that without having to add an additional, superflouos element?
I think I found the solution myself. In this case it would be smarter to use Groups.
