News, Finance, Sports and Travel Apps updated with hints

So those 4 apps got updated today. There's obviously a rather long list of improvements for each one, especially when it comes to new content. One thing that stood out though is now each of those apps now has a small hint that appears at the top:

"Hint: Swipe down from the top or right-click for more content"

Do you think small tips like these should be added to more places?
