When you're viewing a collection set of smart collections in the Collections panel, if you duplicate/rename/delete a collection set, the viewport seems to scroll up to the bottom of the highest open collection set... The viewport should stay put on the collection set I am currently working in during these operations and not scroll for me. This can become very tedious as I make 5-7 smart collections with every collection set that I create!
