The job is already done with "bookmarks import & export"extension. It's just a bit annoying that Help says there is such function in Opera settings, while that's not true, took me some time to find the solution. But all OK now.

My Opera is 28.0

Opera help says there's an export function in Opera->Settings, but I cannot find it, no matter how long I look. Import bookmarks is easy to find there, but there seems to be no export option. Where in the world is it hidden??????

Or is there another "settings" somewhere, the only one I've found is on the drop down list when I click the red O. ?

I need to export Opera bookmarks to a file, that Chrome and Explorer can import.
