With the addition of visual bookmark manager to Chrome (previously called Google Stars) comes new attributes such as bookmark notes and images. I have looked at Chrome Bookmarks API (@ https://developer.chrome.com/extensions/bookmarks) but I couldn’t find anything related to notes or images. So how can we manipulate those new attributes?
I can confirm that these attributes are synced so they are not temporary data.
I figured out that the API to manipulate notes and images (and other metadata) resides in bookmarkManagerPrivate so they are not available yet for developers.
