Rename Tags

Can we please have the ability to rename both the grey tags and the blue flow tags?

Some of the tags we have would be clearer with better wording or different word orders than what exists on them, but we cannot edit the name of the tags. Only delete, or create.

Some of these tags have hundreds of people attached to them so it is not feasible/realistic to delete the tag, re-create it, and then re-add it to all of those people - editing the tag name(s) would be much more practical and efficient.
