We discussed several Views per Entity, but so far did not go into implementation. One reason is that it will make Fibery more complex, since now you will have a selector for Entity View and we are not sure it is a good idea to have it. You can hide fields here now, but do you really need several Views per Entity? Can you provide your use cases?
We also try to solve explanation problem with Fields description. It was released last week. You can add a Description for any field and explain what it means.
