I have tiddlers each associated to an article I'm writing.
They all have a tag 'ContentItem'.
They have a tag representing the status: 'PhaseSetup', 'PhaseFreeWriting', 'PhaseOutline', etc.
They start with 'PhaseSetup'. Then they move on to the other statuses.
If
no article is in 'PhaseSetup' status — hopefully they all end up in
'PhasePublished' status — when I create a new article I have to recreate
the tag 'PhaseSetup' again (and change its color).
How do I prevent tags from being deleted when there are no tiddlers left with that tag?
Do I have to create some hidden tiddler that has that tag? I don't want these hidden tiddlers to show up in lists.
