Sorry to point this out but no-one except Opera own their desktop browser (given to us for free) and we certainly don't have any claim or rights to the features of the previous version. Opera can do whatever they like to their browser so stop assuming they owe you as your comment implies.

But we also don't need to use their browser. Why should we? The current Opera is nothing to get excited about. I can use Chrome/Firefox/IE instead and it's no big difference. The older Opera (<=12) had outstanding features which are missing in the current version. These features were the reason some people preferred Opera. Even simple features/settings from old Opera are missing.

I tried the current version (25) and it can't even handle a lot of open tabs. I always get memory warnings. It's unusable for me.
