I have been working on prosemirror for about 20 months now, building rich text editors for various needs.
I thought of creating a npm package for some of the most used features in rich text editors in my leisure time, so for now I came up with implementing text-direction, text-alignment and line-height features. If anyone is in need of it can use it.
Feel free to try it out and give your feedbacks. I have put a detailed explanation of how to use the APIs exposed by this package in your editor, so you can check that out in the github README.md file
