I would include the FeedView and the above mentioned mvux interfaces into a kind of tutorial for beginners because I did struggle with it at first also. Hard it is also because where are not so many information about mvux beside the uno docs. While the mvux docs to this list and state things are quite detailed. I would add there some details i was missing and found out while learning.

In the Dokumentation to FeedView there is a listview nested in it and i got also a GridView working with it.
The open questions i would have to this:
On the FeedView we do have properties related to drag and drop but also the nested view do have this. In which case is at 4 which task we would actually use these properties on the FeedView itself and when on the nested view? What is the usecase of them?
