Referencing attributes inside note content

[mikkel1156]

While I know that promoted attributes are the way to go, having a nice and cleaner way to update the attributes of the note inside the actual content would be nice. Actually surprised I haven't found an issue mentioning this (or maybe my Googlefu is bad).

Couldn't find a specific thing that could help with this inside CKEDITOR (from a quick look at their docs), so any resources would be appreciated if I want to do a PR.

I imagine it would be some custom HTML element being inserted, that on change (or focus leave) will update one or more of the attributes. This would also help with the clutter in the promoted attributes that some people have mentioned.

Thoughts?

Edit: This is the only issue I actually found closely related: #1950
