the updated "your stuff" Library sorting is trash

I’d love to submit feedback, but my options are ask a question or report a bug. They way you have now changed Express library views to resemble the mess in the main programs is infuriating! It used to be organized and closable by category. Now its a bucket of everything and no category is closable (down arrow). We have MASSIVE libraries full of elements. Now I can’t close the huge categories inorder to stop the incredibly slow preview upload to get to the bottom of my library! Do you guys even use these tools!?
