They actually created something I feel is even better. Pull out s-pen, when the action menu comes up, click on the one that says "pen window".
Draw a rectangle or square (for the size of the window you want open), then you'll have a choice (calculator, clock, youtube, phone, contacts, hangouts, internet). In your particular case, you'll be choosing internet.
You can do this with the multi-window, which means multi-tasking with 3 apps at the same time. I use multi-window more often than pen window, but in those few instances that I'm browsing for competitive pricing on a product, texting the info to someone, and also trying to get the calculations on total pricing, including tax...etc., to see if I'd have savings...yeah, works great for that rare instance.
