Twitter users will now be able to add bookmarks.
What are they needed for
This way of saving tweets is much more convenient than using "likes", which all users see. "Bookmarks" are only available to the account owner.
The option of bookmarks was promised to us in October of last year. Soon it will appear in Twitter apps for Android, iOS, Twitter Lite and mobile version of mobile.twitter.com.
Where to find
Tweet can be saved using the Share icon. In the same way, it is deleted deleted. You can view saved tweets in the "bookmark" in your profile. All bookmarks are deleted through the "More" menu at the top of the bookmark ribbon.
