Thanks for the replies; helped me scratch an itch that I've had for a while.
I've made the change from 'Book Marks' [and that bar] to Pseudo-Book Marks, using the Speed Dial page, and now that I'm happy with that for my couple dozen 'Book Marks'....AND...found out how to pass new ones back into the main program, from my V/M, 27 seems just fine.
I'll probably uninstall 28 and 29. One of these days I suppose when I look at 'About Opera', 27 will miraculously have become 28! That's how my 26 became 27.
Oh, Leocg, I've been to those blogs, and do understand the differences; just wondered about decision making
