If there's something that I really miss in the extensions is the extensions for chat apps, such as skype, facebook messenger, telegram, whatsapp. I'm speaking of the option to share a photo to these apps directly from photos, or sharing a link from safari. It works so great with Evernote and Flipboard and I wonder why there's no (yet) extensions for these popular apps. Is there a reason behind it? Apple isn't providing extensions for Chat Application?
