Feature request: I would be nice if on the category search results page (both a list of results and the no results found page) if there was a link/button that would take you back to the search page with what you entered already selected, so that you could modify it (to, say, make it more or less restrictive) without having to recreate it. It looks like the search terms are saved in the URL so I'm guessing it wouldn't be too hard to engineer.
When I use the browser back button, half the time, my search settings are wiped out (Safari/iOS). Thus my request.
