Hi there!
My suggestion is for adding a feature that allows users to Show or Hide Pages in the Pages panel located on the right side of the screen. This feature would be very useful for hiding pages that we don’t need or want to see, without having to delete the content on those pages.
I have created a rough mockup below of how this feature could work. Perhaps a hidden icon could be added at the bottom of pages, and when clicked, all of the pages that the user marked to hide will show again.
I believe this feature would greatly enhance the functionality of Pages in Figma.
