@jelleag thanks for the PR but can you privide more information then just multiple tags?

preferable nice to have screenshot/gif since it's little hard to understand what exactly this feature does?

Sure!

For a project I needed the ability to enter more than one value per tag. In my case, I wanted the possibility to enter two values, in which the first is a key and the second is the value. I have made a more universal solution, in case others would want to use it too. I've added some screenshots below for illustration. Can imagine it's a particular use case, and maybe outside of the scope of this package.
