Most promising ToC plugin I’ve used

The guys behind this plugin are definitely onto something! Very good plugin, and support is over the top despite it being a free plugin.

I’ve switched from Easy table of contents to LuckyWP Table of Contents, because easy table of contents had quite a few bugs, and had not been updated for a while.

I had an issue with lazy load affecting the scroll with LuckyWP ToC, created a support ticket and within hours the problem was fixed, 5/5 stars is very well-deserved.
