First Letter Jump in Collections

As I make more use of the Collections feature (3100+ and growing), I find having to scroll to find what I am looking for to be time-consuming and error-prone. Could you add the “first letter jump” feature where the first letters are listed to the right of the screen where clicking one takes you to those collections starting with that letter? This would also make it consistent with how the Library screen works.

First, we need the ‘Letter Stack’ in the Collection.
