Today I’m releasing an update to bring compatibility with the fantastic new Glimmer Topic List system
This was essentially a rewrite and took days.
You must be on latest and enable Glimmer Topic Lists.
If you don’t do this you may get an alert pop-up nag 
If you think Topic List Previews is awesome & I did a great job, you can buy me a coffee 
NB: Unfortunately, due to the extensive rewrite, if you’ve been using some CSS tweaks, you may have to redo some of them.

thanks to @david for extending the awesome new Topic List API to accommodate my requirements.
