While we are at is wouldn’t it be nice to have one identical way to attach attributes/values to anything ? Front-matter are just attributes attached to the note itself… There is a large number of request for attribute to be placed on tasks also like due-date and such, who would benefit from being scoped to the task they sit in. I would see huge interrest of having link scoped attributes as it would also go in the direction on the very very numerous “typed links” threads.
From the moment such a capacity exists in the core to attach key value to a note, paragraph or link, plugins can really use those to their full potential and build usecases limited only by imagination. Plugins they won’t have to re-parse the notes themselves or introduce random and often incompatible syntaxes to do basically the same thing.
