I see a lot of comments that Opera 15 is not a finished browser, we should wait until the older features are put back, it's in a development stage, we should be patient and stick it out with version 12, etc. This way of thinking didn’t work for me. Since Opera 12 is a dead-end, I had to find an alternative and long-term solution. I tried Opera 15, but uninstalled immediately, just like its similarly inferior brother, Chrome. I tried several other browsers and eventually wound up at Firefox. After searching for some addons, I achieved a comparable functionality with it.

It was a bad decision to come up with this Chrome-clone too soon. If indeed it’s planned that something of the old Opera will return within the new engine, then they should have waited a little longer rather than alienate a lot of users by a half-baked product. (It is also possible that they have no intention to improve it too much and will just go with the crowd and remain one of the browsers for dummies.) I don’t know if I will check back in the future to see how things worked out once I decided to migrate to another browser. As I read other forums, I'm not alone.
