This utility a Twitter client developed for Mac that enables you to organize the information you get on your account. The program allows you to create custom timelines showing posts from some of your friends, certain mentions, the posts you liked, etc.
After you log in to your Twitter account, the application gives you access to several default timelines (Home, Notifications, Activity, etc.). You can add new columns with just a few clicks. The program allows you to create special timelines (or columns) for another Twitter user, a certain mention (for instance, posts related to the "NBA" term), and many others. You can always remove columns from the main window of the app, rearrange them in any order you like, and refresh their content.
Another advantage is the fact that you can use various shortcut keys to check a user's profile, add new columns, retweet, immediately use the search tool, etc. You can also customize the appearance of the interface by changing the theme (Dark or Light) or opting for another font size.
In my testing, the utility worked flawlessly. It updated the content in real-time and didn't use many CPU resources.
In conclusion, you should definitely install this free program on your Mac if you use Twitter on a daily basis.
