Here is a pro tip for Twitter users: careful what you wish for. After years of jokes and countless tweets begging for an edit option, the bird app has announced that it will begin testing the feature with one caveat: It's going to cost you. 

Select Twitter Blue subscribers will have early access to the feature, once its internal trial run is completed. Twitter Blue is a monthly subscription service that provides access to exclusive features such as ad-free articles, undo tweet options and custom navigation among others. 

So how does it work? Once a user has published a tweet, they will be able to go back and edit the text multiple times, but the option will only be available for 30 minutes after publication.

Other Twitter users will be able to delineate between original and edited tweets via icon, timestamp, and label. They will also be able to see past versions of the tweet.

"For context, the time limit and version history play an important role here. They help protect the integrity of the conversation and create a publicly accessible record of what was said," Twitter said in a blog post.

So if you were hoping that typo or factual error would go unnoticed, other users will still be able to see your past tweets. They'll just also be able to see that you made an effort to fix it. 

While users have been pushing for an edit button for years, the company said its motivation for launching the feature is to make the Twitter experience "more approachable and less stressful." 

"You should be able to participate in the conversation in a way that makes sense to you, and we'll keep working on ways to make it feel effortless to do just that," Twitter said in a statement.
