Page editor for users

Hi, I've started working with Grav recently, but I'm missing one important future for my potential users. I installed users and groups plugin, which is great and I want users to be able to change pages - every year rewrite some parts etc., but they are not familiar with markdown and html. Is there any posibity how to get an editor which would look like preview window I have now, but with editable futures?
Thank you for your replies 🙂
