Actually, I choose https://wordpress.org/plugins/custom-sidebars/
Add everything is working great.
Before, using Content Views Pro, I had a 1.3 second delay (on average), for unused css on PageSpeed.
Now using WP Show Post, and the built in features of GP Premium, I have only 0.15 second delay for unused css on PageSpeed.
You now get (earn) $75 from me every year.
Thank you for your hard work.
