Collection views in Photo Stream

Hi,

some ideas about how collection are displayed:

As is: I can click on one collection and it shows me all the files that belong to that collection.

I would like to be able to
(1) hide the collection that I select from the photo stream
idea: I am currently managing the picture that I am planning to delete later with a collection “to delete later”. Once I add one pic to this collection, it would be nice to have it disappear from the list or make it displayed differently

(2) select multiple collections
idea: I want to see only the pictures of collection A and B. As of now I cannot have multiple selection of collections

(3) I want to color-label my collections
idea; When I select pictures, it would be nice to have a visual feedback about what label they belong to. For example, there is the heart icon for the favorite pictures or for the “remove from workspace” button. maybe something similar would be nice to have.

(4) I want to be able to add the collections to the “Thumbnail Label” feature
