Current Okular behavior:
When you click a bookmarked page in the sidebar while viewing another page, Okular navigates to the bookmarked page. To return to the previous page, you must either remember the page number and type it manually or scroll back to it. This is slightly cumbersome and disrupts the flow of work.
Feature request:
When a user clicks a bookmark in the sidebar, jumps to a page by typing a page number, or navigates to a page far from the current one, Okular should record the current page. It should then provide a button (preferably in the sidebar or at the bottom of the document) that allows the user to return to the previous page. Additionally, after returning, the user should be able to navigate back again to the page they jumped from, enabling easy back-and-forth navigation.
