Anyone aware if there are any such Grammarly-like alternative add-ons currently working in Thunderbird? Or if there would be major barriers to porting this, or similar, add-ons to MailExtensions?
I know the WebExtension API isolated a whole lot of people but it would seem there is still some hope as some useful extensions that are born as WebExtensions, rather than deciding extensions requiring conversion or rewriting, can still be beneficial despite all the limitations of WebExtension APIs relative to previous APIs.
