Hello! It's now possible to close affiliations in SKY view. However we have not yet addressed the other feedback listed here, about filtering the list of affiliations related to a record to only show the open ones. We intend to deliver that functionality in the near future, starting with the filtering options that were available in classic view. You can track that idea separately, here:

Wendy, we love your idea about automatically closing all of a grant's affiliations when it's done. We'll think about that some more, too.

Agreed! The ability to close all at the same time like classic would be great. But it would be even better if you could close a grant, and have the system automatically ask if you want to close all open affiliations with a "yes" or "no" button.
