Does what it says on the tin.

medium sized site.
moved 2000+ post from one category into several categories.
No issues.
(yes I agree it could be tweaked with css (hence 4 stars)- why bother, admins only need it work and certainly does that.)
Thank you.
Tip to Developers “Run some do tests and update the Supported WP level as some folks will not use a old / non updated plugin.”
