As long as Atlassian won't provide a better experience here, it would be nice to have some options and settings in advance to what is there today. Just some thoughts:
  • user setting to select if you want to be notified by mail & notification center or just NC
  • daily summary eMail for favourite spaces (nobody needs the full summary)
  • unwatch all in the personal list: after a while it would take ages to clear the list 1 by 1
  • improve watching for attachments
