Is there a good place where notable new extensions are highlighted?

Not that I know of. It is a matter of chance to discover new extensions.
It would be a good idea include an online "vote" system in the own extension, to deciede the best ones / or the most asked for when they are finally created. BoldLuis (talk) 12:20, 28 April 2020 (UTC)
