Often times I'll search for specific pages (or use a saved view) and then start editing a page. Once I'm done I'll return to the list of pages to update a similar page and have to search or open the saved view again. I'd love to be able to "return to search" rather than return to the full list of pages.
This should be able to be done relatively easily with something like session storage or even a cookie. Given the addition of folders as a first class citizen, this feels like an even bigger need to make those really useful.
