Is bookmarks sync compatible with link.opera.com or is it completely seperate?

For me it doesn't sync my old bookmarks at link.opera.com. Will this going to work in the future perhaps?

I've checked setting for long menu long press and it's search assistent. Opera is probably default for this.

Perhaps this issue with back button isn't related to opera at all, but I've just recently start to use it again (because of the bookmarks) and notice this problem.

It seems that opera takes over control of phone capacative menu and back buttons when in home or application screen. When in any other application buttons work ok.
When on home or app screen, back button doesn't work at all, and long pressing menu button opens opera. This occurs also if opera is is closed normally or force closed from apps settings.
