TagWrangler is a transformative plugin. It makes tag management a joy. Tags are great for many things, but key-value metadata also is useful.
I love tag wrangler because it gives you the “stratospheric” view of all tags. Really nice and so useful to help clean up tags (misspelled,wrong terms used, etc.) whether from imports or due to just debt accumulated over time.
With metadata, we really should know in advance our terms to query them. This makes it very difficult to get the big picture view. It also means it will not pick up fields with spelling errors, wrong variants (“links-to” instead “linkto”), etc.
Furthermore, what makes TagWrangler so useful in this regard is not just presenting a survey, it allows you to edit the tags in-place. These two together make for a very powerful tool not just for resurfacing, but also note management.
I love going to the tag view and at a glance understanding and having full control over the tag data model of the entire vault. It would be great to have the same for metadata.
