I think there are two important points to mention here.
The first one is for new people and those who use the platform for the first time (new comers) and wants write an article. They should know some things about what is called Markdown, or know about how to load template, which is important to improve the appearance and final results of a post, or comment.
The second is the development of tools of writing or editing in general in the platform, and there are many notes and ideas here, including changing the color styles, the ease of setting up tables, changing images and a long list of other important tools.
