Earlier “Tag Wrangler” worked fine for renaming tags but since the new bases have been added it’s not sufficient anymore. It doesn’t rename the tags used in base views.
Example: Using the tag #Idea as a filter in a base view and then renaming it to #Invention will just update the #Idea to #Invention inside the notes (files), but not in the base views which have used it as a filter. You have to manually rename the filter #Idea in every base view to #Invention.
I just can’t trust using tags for base view filters. The semantics/meaning of a tag may change over time and I have to be able to mark this by giving it a more precise (e.g. more concrete/abstract) name.
