I have been adding some tags to notes, but as things go some tags are not useful. For ex. I use the 3yr lectionary and I am creating a note for each day with propers and etc. During the season after Pentecost, these are also called Propers, and numbered 1-29. However, there is year A, B, C. I started taging the Series A days with "Series A", which is sensable. And also tagging with the season: "Easter", "Christmas", etc. However, as I came into the season after Pentecost I used the tags "Series A" and "Propers" which is not all that helpful since "Propers" would automatically include A and B and C. I changed "Propers" to "Propers A" creating a new tag, but I'd like to remove "Propers" from the list. In fact, "A Propers" might even be a better tag.
Any suggestions how to remove or delete unused Notes tags?
