Agree. I know a lot people still think 3D Touch is a gimmick, especially using features like Peek and Pop. But I use it quite a lot. But one of the apps I really wanted Peek and Pop to happen with, was Twitter. Strange that they didn't do this earlier. But better late than never, right?Finally! Peek is so useful for previewing links. I use it all the time in general on all sites.
I'll be using this a lot, that's for sure. It can be so handy, since you don't have to keep tapping tweets to see the comments for example, or to go all the way to a website and then having to go back again. It's much easier to just 'preview' it with Peek and let go of the screen to go back. It's a timesaver to me.
