I recently changed my actual browser to Safari (😱) because since mobile Safari allows extensions, I could have a single extension (Keyword Search) that would allow me to define keyword searches that would work on both desktop and mobile. And before that I had put a great amount of time into doing custom scripts to do the same thing.
So it's a BIG deal for me (and other users) to be able to type something like "rot Ghostbusters" and get Rotten Tomatoes results for Ghostbusters....and have that work on both desktop and mobile browsers! It saves MANY steps 🙂
