I use snippets as short codes that stay active for a periode, and then I stop updating them. It will typically be an index to a series of blog posts, that is updated when a new posting is added.
But at least for a number of them, when the series is closed, it is closed and is no longer updated (or at least no new postings are added.)
The snippets listed under my Snippet button keeps growing. In one way or another I would like to be able to remove snippets from the snippet button, without removing the snippet (and I guess deleting indexes if I delete a short code snippet). One simple solution could be to tick it as "inactive" or something similar on the "Post Snippet" page, thus removing it from the list under the Post Snippet button.
