Add support for mentions.

Will be good if we can use this framework for hashtags and for user mentions.
(e.g. @Vista1nik)

Hey @Vista1nik, thank you for opening this issue. Really appreciate it!

🤔 so, this could totally be implemented and be like a totally separate component. Would you like to open a PR? That would be awesome. If not I can take a look at it later this week.

Cheers!

As I was exploring the internet, there is no better solution than this component to process hashtags. I couldn't find any solution for doing the same for mentions. It would be great if we can have that working in this package.
