I'm dreaming that some day social networks like steemit will give us an advanced tools for the customization of the layout of the article.. In reality it's not that hard at all. Not too much code and storage needed to implement this. I wonder how many writers and bloggers would die to have such kind of possibilities. And what a great possibilities could be for the font makers to promote and sell their fonts here. For example, if you have bought the font it will appear in the editor. This could be BIG.
