Only ones EVER in this forum that want separate speed dials are Moderators and Opera Software employees. No one - zero, nada, nobody wants different ones. Speed dials are start page bookmarks and they should be in sync with anything sync'ing them.
If not - there should be an option. and given Opera's history of "more options the better", the only thing to think, is there must be some weird programming barrier or laziness that keeps them from giving the users the #1 request since speed dials were put in the software.
