Two big efforts to test horizontal swiping over vertical feed scrolling interfaces may offer hints from Silicon Valley about where mobile UX design is headed.

Be smart: The popular "Stories" format that was created by Snapchat and then adopted by Facebook-owned Messenger, Instagram, WhatsApp and the core Facebook app, have used this function for a while to allow users to advance through more content more quickly.

  1. YouTube has been rolling out a new feature on iOS that will let viewers swipe right or left to navigate between videos, according to an interview with Popular Science. The feature, known internally as “swipey watch,” has been two years in the making, and will be coming to Android devices later this year.
  2. Instagram was in a PR tizzy in December after reports found that it had been testing a new horizontal tap-to-swipe design for months. The company told users that it was just a test that accidentally rolled out widely.

Why it matters, via TechCrunch's Josh Constine: "Tap to advance...eliminates the need for big thumbstrokes on your touch screen that can get tiring after awhile. It also means users always see media full-screen rather than having to fiddle with scrolling the perfect amount to see an entire post. Together, these create a more relaxing browsing experience that can devour hours of a user’s time."

Louisville Metro Police Department said two officers were shot downtown in the Kentucky city late Wednesday, just hours after a grand jury announced an indictment in the Breonna Taylor case.

Driving the news: Metrosafe, the city's emergency services, said it received reports of a shooting at South Brook St. and Broadway Ave., near the area where protests were taking place. A police spokesperson told a press briefing the injuries of both officers were not life-threatening. One officer was "alert and stable" and the other was undergoing surgery, he said.

Former Vice President Joe Biden on Wednesday condemned the grand jury indictment of a Louisville police officer who entered Breonna Taylor's home in March in a botched drug raid that led to her death, saying in a statement the decision "does not answer" for equal justice.

The big picture: Biden called for reforms to address police use of force and no-knock warrants, while demanding a ban on chokeholds. He added that people "have a right to peacefully protest, but violence is never acceptable."
