thank you for your help!
Yes, they are. And magically there is the missing Selection Menu. (Without any changes…) I just had to sleep
Maybe I just should have clear the cache, although I was in Development mode. -.-

Edit: I tried one more time: Clearing Chrome browser cache solved the problem.
Just for the notes: The Menu will only appear if you select the document node. If you have a text node active or something else it will disappear and replaced with the aloha settings
