Twitterrific 5 has just received a fairly significant update that includes several new enhancements.
First and foremost, a bunch of stuff has been tweaked in the backend in order to make everything run much faster and smoother. More list management options have been added; including the ability to edit details and privacy settings, create all new lists, and add or remove both lists and users from said lists. Support for viewing images in direct messages is also a thing now, as is the ability to copy content directly from the share menu. Finally, and perhaps most importantly, the app now supports live-streaming of the timeline when over wifi.
You can grab the update for Twitterrific 5 right now, or if you're new to the app you can download it for the temporary sale price of $0.99.
