How do I contact an extension developer to pass on (in this case, unfortunately, negative) feedback. I've tried going through GitHub, but I've had no (good) luck.

If you want to post a review - see under 'Rate your experience' on that extension's site.

Under 'More Information' you should be able to see a 'Support Site' and maybe even 'Support Email'

(as you don't mention the name of the extension in question, I can't check this ... )

happy112, I couldn't find the required link from my copy of "Brief," But I did find it on the entry in the Add-ons Collection. The post has been posted.

Many thanks--I was worn out yesterday, so my mind wasn't where it should have been.

So this is the add-on you were talking about :

And the 'Support Site' is right there where I said it would be : under 'More Information' ......
