I found chromium issue titled "Allow extensions/apps to sync their own settings" that has status 'Fixed'. It's from December 2011. So, does it work? If so, how does it work and where are the docs?
Last time similar question was asked in 2010 and then the answer was to use bookmarks hack. I think it's time to have an update on this topic.
Update: I just found these docs for experimental chrome.storage
API. Is this what I'm looking for? Do we have any new alternatives (other than bookmarks) till chrome.storage
goes stable?
