Ability to toggle tag filtering to be exact tag only

I like the amplenote tagging system, especially over folders. There is one small caveat, sometimes I only want to view the items that match an exact tag and not all the subtags underneath since I don't put all notes at the exact same level (like level 3 or something). I am thinking of something simple. If the toggle is on, just update the default search that is provided when you navigate to the tag on the left to include the not as part of that search.

e.g. if I click on areas it would have the search be `in:areas`, if the toggle were on then the search would be `in:areas,^areas/`.

As an extra benefit it would be nice to see the flat number on the left in the tag list, but that would is not necessary.
