Edit page.title and header items

[davay]

The editor works perfectly well! I try to establish a robust way to collaboratively edit Grav sites and this plugin is definitely a big piece of this puzzle. I wonder if may be it's achievable to make this plugin edit the page.title and page.header items as well? I understand, that it may be another plugin with just contenteditables and not the fancy MDE, but I'm yet not skilled enough to write my own. 🙄
