We just pushed an update that includes the following:
* Feed is more compact now - less scrolling is required! Also, all posts on the feed are now shortened by default, and a 'Show Less' option was added so you can collapse long posts if you're just browsing the feed.
* Performance improvements - everything should feel more responsive and less laggy.
* Post action buttons (like, follow, etc) now more accurately reflect the action to be taken. For example, the Like button now says "Like" and after you like a post, it will say "Liked." The design of this is still a work in progress.
* more small design changes
Enjoy!
