@avl, I'm not saying you are wrong, I'm just want to phrase it as not right.
Think of the user experiences, Opera is a great software, and I like it.
However, I'm suggesting to add more functions, for example:
Creating a final user interface, which manages the item that you need to synchronize can be very helpful, both for users and developers.
Anti-human means you guys are not fully think though (functions, user experiences etc.). I'm feeling like I'm using a prototype, which made me really disappointed.
I might leave Opera for a while, until the next update, or the update after, or ...
