Request: Add sync status indicator to addon icon

It would be great if the addon icon provided some kind of visual indicator that showed whether the current local bookmarks were synced with the server.  Basically, this is a clean/dirty indicator that shows whether a synchronization is needed. It would go to dirty any time a local bookmark is modified, added or deleted, bringing the local system out of sync with the server. It is a visual reminder that the local system needs to be synced to save the changes to the server.  You could, I suppose, make this optional for people who choose to enable the autosync feature. For those who are not using autosync, such an indicator would be very helpful.

I am categorizing this as Eversync - Chrome, but the request applies to all the browsers, and really to any version that syncs with a server.
