Thanks for the reply, @codinghorror! Automatic merging of singular vs. plural would be great.
One more thing that might be useful based on my experience is a new tags queue so it’s easy so spot them and either a) approve them as is b) merge them with something else or c) delete them.
One of the problems we have now is identifying newly added tags. Because they’re not anywhere unique it becomes a hunting game of pouring through a sea of words each month looking for similar words/phrases.
Having a new tag queue - or being able to sort tags by date added - would be immensely helpful for keeping things nicely organized. Or, at least selfishly, for us.
