Add search by letter within Collections

I have a Collection with over 300 entries… when sorted alphabetically, there is no way to skip to titles starting with a letter. (like jump to titles starting with “R”). The Library tab has on the right side a letter search which is exactly what is required.
Can this be added to Collections lists?

There is an existing request for this. Rather than splitting votes over multiple threads, it’s better to add your vote/comments there:
