Today Tapbots released a big update for Tweetbot on the Mac. The main addition is the enhanced media view that is already present in the iOS version. When viewing a timeline, tapping ⌘F now allows you to switch between a text and media-only experience. The media view displays a stream of images and videos from tweets in the timeline.
Tweetbot for Mac also supports cover photos for individual profiles, another feature that has been present on mobile for a long time. Viewing the details on a specific tweet will now show how many times it has been favorited and retweeted.
