I propose a tag panel more dynamic with the possibility to annidate tag with a click and the possibility to rename a tag in the panel and update it in all files where it was used
Current workaround (optional)
At this moment this option are all manual and mechanical to apply for every file
Renaming does update all the files where the tag is used. Complete happiness for me.
Tag Wrangler doesn’t have an annotate option, but it can create pages based on tags: right click the tag and choose ‘Create tag page’, which you can add notes to.
