Tags, like backlinks, are used to create a links, bind files/ideas, add context/data to be able to find or recall later, but that’s the very basics of what they can be. Within a specific UI, you can also use them to explore, collect, read, reflect, search, aggregate, filter content that has these tags/links.
Doing this in the search panel isn’t possible currently and a tag version of backlinks panel would be a halfstep to what could be.
So I’m suggesting tags (and backlinks) could have their own “home page”. A hub that shows all the instances in a readable view.
So you’re on your “onCreativity” tag page. In it is an embed of every paragraph that this tag appears in. The list of embeds could be filterable & sortable, etc.
The overall point is to have a more readable & useable context of your instances/mentions that allow you to actually explore, read, discover your writing in novel views & contexts.
With powerful filtering you’ll be able to create a thread of very novel/meaningful paragraphs (depending on your header discipline) which prompt and excite ways to remix and connect these ideas.
Perhaps you can also have an “new note” button within this view, which opens a blank note in another pane which has the tags/context of this filter (the info/context it was inspired by).
Perhaps these pages could be where you have analytics of sorts on the tag/backlink.
edit: this could also be a place where aliases, nicknames, attributes, settings, etc are explored & edited. The home page is the place for all things related & about this tag/link.
