You might have read my previous [blog-post] regarding sharing and contributing custom widgets to the community.
To go further, I will present a webinar on Tuesday, July 18 at 9:00am (Pacific time) / 12:00 pm (Eastern time) where you will learn how to use the framework provided to create new widgets, but also how to download existing widgets and share your creations.
Too bad you missed the webinar, but you can find the recording here .
