Twitter has rolled out testing on a feature they're calling Statuses.
Statuses will be taken from a pre-determined list of choices like: Traveling, Vacation Mode, A Thread, Counting Down, Shower Thoughts, and more.
When you use statuses they can determine the fact you're away like traveling or working, as well as add some extra value to your tweet like warning users that you have a hot take or it's the start of a thread.
No word on when the feature will expand to a wider audience.
