This page displays the pages which you're the owner of only, to give you an uncluttered view of everything that you're working on.
It's filtered to only display pages that're owned by whoever is viewing the page so it can be duplicated for each member of the team. Any changes that're made to the database views inside a copy of this page won't affect the other copies of these views. However editing the properties of the columns themselves e.g. deleting, renaming, changing their type etc. will affect the other views.
