Tweetbot updates its Mac app to add its new Topic feature, which is designed to link related tweets together in a more cohesive and easier way. You can access the feature by tapping on the gear menu in the New Tweet screen. The good thing is your tweets are stored and need iCloud so you can jump from your Mac to your iPhone or iPad to continue tweeting.
Some of the other new features include Collections support, which lets you save tweets linked together in a topic; better quote preview in the compose window; remove play/pause button for video playback and instead have clicking on the video toggle play/pause; as well as a slew of bug fixes. The direct link to the Mac App store shows the other fixes for the app.
