Well ... I find it very useful if we could have groups of Library objects ...
I want to put a title but the title is 3 objects and I have to add one at a time, right in place (Aligned) and it is difficult to stay the same on all levels.
or Houses (Rooftop, House part1, House part2, Windows, Door, Shadow)
Instead of adding one by one. We could group it in the Library and place it as if it were a single object.
