Remove Groups Notification

Please give us the option to NEVER see this giant Library Groups notification ever again. If I choose to make groups, fine. However, if I have a library without groups (either because I haven't done it yet or I simply do not want groups), the huge waste of space is ALWAYS there. I either have to scroll to find what I need or resize my libraries panel, which is unacceptable. Let us get rid of this massive waste of precious real estate!
