As a user, I may be shared to various pages that are no longer relevant to me. While there is an option to hide these pages, this can make page management still cumbersome when I am shared to 100s of pages.
For instance, I am shared to over 400 pages, and that makes it difficult to navigate what pages I want to find. Being able to remove myself from pages that are no longer relevant to me would be a way to make page navigation easier.
