If you scroll by an image and tap on it, then I think the image should open up in full screen.
Right now tapping the image on the feed opens the post where I then have to tap it again. This isn’t the worst but doesn’t a feel smooth. Especially because a slight delay is required between the two taps. If you mess that up then you have to tap it three times.
Liftoff does this :)
I wasn’t the biggest fan of Liftoff’s look but I’ll check it out. I saw they had an App Store release
