I'd like to see an option to add multiple Group Dividers or Section divider.

This would allow users to add people or phone numbers to a group like "Family" "Friends" "Work" "Spam" or "Payment Alerts".

That way it is more organized and I can see all my family grouped together, then a new divider header for Work and see all my work people grouped together.

Even if that number has been deleted from the main menu, when a new text comes in, it will automatically filter into their respected categories.
