Looks like my waiting game paid off. I stuck with old reliable v. 12 until the whole bookmarks madness was worked out. Less than 2% of the browser market share and Opera drops their bookmarks management when none of the guys kicking their butt was doing likewise! This is the kind of out-of-box thinking that made Opera so distinct--no one else is using the type of tools integration Opera has (had?)--but they severely shot themselves in the foot this time.
This is my feeling exactly.
