No way to have h1, h2, etc. titles about notes-up

[Philip-Scott]

I think it would be cool to have something like the title-subtitle thing libreoffice does,

But it would require a different method to add it into the canvas... As you probably saw, the buttons add the tags in two parts, but the h# tags require the # to be on the very first character of the line.

If you want to work on it, i'll gladly help you out if you get suck anywhere 😄

I've added a help section on the editing view in ca074d0

It's not really this item on the toolbar, but it will still introduce new people on how to use it!
