I’ve been using Prismatic as my news reader for a few months and it’s slowly winning over Flipboard, mainly for the quality of the feed it builds for me, based on my interests.
But it also has one nifty UI trick I hadn’t seen before in a mobile app. Although the feed itself is a simple list of stories, the app automatically anchors a story at the top of my screen when I stop interacting with the feed. This way, the title is always visible and you never end up with a cut paragraph at the top of your feed. Pretty neat. You can still scroll down multiple stories at a time with a longer throw, yet the feed will again anchors at the right position when it stops.
Many other apps could benefit from this trick.
