In addition to the current inline notes tagging system, I’d love to have the option of tagging a note externally to the note itself (i.e. by right-clicking on the note within the Notes pane, and assigning the tag there).
I don’t necessarily want to actually see the text-based tag itself (inside my note), and not all notes are contextually appropriate to include them inline.
Additionally, a tag ‘manager’ (say, to review and delete any tags that have been duplicated, bar a typo; or to consolidate tags so that all notes sharing each of the relevant tags are now merged under one tag) would be a great way to augment this Notes-pane tagging approach.
