Hello Michael,
Congratulations on the new beta version. Looks very good so far ...

The grouping feature is very useful for already existing objects.
But how can I move a newly drawn object into an existing group?

Addendum - I found the logic:

1. draw new object
2. assign name (if needed)
3. click on group to which the object should be moved.
4. done

Simple but effective
