Goodmorning everyone,
browsing the official Nova website, I found two problems that I wanted to report.
I have not found another place where to report them and if there is a specific place where to report them I would be happy to have it. 
I leave attached the photos/videos of the two bugs I identified.
Both bugs have been identified in this section of the site: extensions.panic.com
I hope they can be useful. 
See you soon!
