Twitter has added two new tabs to its main, front-page interface, each with new features.

The company calls the first the “@Username” tab, and it contains mentions, retweets, and favorites from other members. The second is called the “Activity” tab, and it highlights tweets your contacts have endorsed.

The @Username tab is actually a repurposing of the old @Mentions tab, but where the old interface only showed the @mentions you’ve received, this new one also includes any of your own tweets that have been retweeted or favorited by other members.

Twitter has eliminated the old Retweets tab because everything it used to contain has been moved to this new one.

The Activity tab is actually somewhat similar, but instead of your own tweets, it features tweets by others which have been retweeted or favorited by the people you follow, as well as new people your current contacts have recently begun following. It’s a good way to see what your current contacts are interested in, and to find new people to follow.

None of these features radically change the way Twitter works, but they’re welcome features for folks who use the website instead of more powerful, third-party social media management apps. The features don’t appear to be live for everyone yet, but they began rolling out today, so keep an eye out.

And if you’re not clear on what terms like @Mentions mean, we have a list of important Twitter term definitions you might want to take a look at.
