Say you've applied a search filter in the grid view of your artboards. Then, you click on one of the results. You realize you want another artboard that matches your filter, so you want to go back to the filtered grid view to find another artboard. That's basically the idea of what I would like to accomplish as a user.

Right now, once I filtered the view and navigated to one of the resulting artboards, I have to filter all over again. It adds quite a bit of cognitive load (need to recall what the the thumbnail of my previously-selected artboard looks like, because the names are cut off with ellipsis).

Hence, it would be quite helpful if we can simply press 'back' to go back in browser history and return to the filtered results.

Maybe add the search results in the URL bar:

xd.adobe.com/spec/<unique_code_of_document>/grid/search?<url_encoded search query>

Obviously, pressing 'back' twice would allow the user to go back to the unfiltered grid view.
