Tapbots' Tweetbot for Mac already has a reputation as the desktop Twitter client for media hounds, but a just-posted 1.3 update should make that especially clear. Like its iOS counterpart, the Mac app gains a dedicated media timeline: start a search and you can spotlight only photos and videos. There are a few perks for the vain among us, too. Tweetbot now supports profile cover images, and a redesigned tweet layout shows the counts for those inevitable favorites and retweets. So long as $20 isn't too much to pay for a dedicated social networking tool, 1.3's greater media savviness is waiting at the Mac App Store.
