Just to clarify. If I sync my calendar between devices, I expect my calendar entries to be available on all devices and not to be able to edit a calendar entry that is saved on some other device (Opera "sync"). What a mess this would be. This is not symantics, this is marketing and a very bad one which makes it even worse.
No, Opera doesn't sync, it allows access to Opera bookmarks/tabs/etc. of other devices (which is fine for tabs for me, but for the speed dial). And it's also not "speed dial", i.e., speedy, if I have to do navigate to another machine and click the "speed dial" there. This is not speedy nor is it sync.
What Opera calls sync doesn't help me because one device, which currently has all my speed dials, will be shut down. While it will remain in the Opera cloud, this is not an acceptable solution. My current option is to open all speed dial entries manually and save them at the new device (again, hardly synchronization). Not an option.
I guess it's back to copying config directories from the file system again. If someone knows of another solution, I'd be glad if you share. Thanks.
