Opera with its version 15 release seems to make the same error as Microsoft did with its Windows 8 release: too many changes for long-term users! Opera 15 is crap. Download size is more than twice as much as of version 12.16. The overall look and feel smells too much like Chrome. I recommend long-term users not to update – stick to latest version 12.xx ! If opera were an open source project it would be a good time for a fork. If the smell is like Chrome I could use Chrome directly – no need for opera anymore!
