The new "feature" of always opening the collections window to a new blank collection (in 4.2 beta 6) has broken the links I have saved in Favorites to particular collections. These used to work correctly, and now they all open to Unnamed Collection:

In addition, the collections window also displays "unnamed collection" when a layout containing the collections window is loaded (at startup for me). It should be the show the same collection as when the layout was saved.
Also, why was this feature added? To keep people from accidentally modifing their existing collections? There has to be a better way to prevent that. I really liked that the Collections window always opened up the the last collection I was working with. Now I have to select a collection every time. Can I register my dislike of the new feature?
