careful what you say ... Opera invented, innovated and drove a load of these features then, because they were loved by too many and management were stupid, they removed the more useful ones to the detriment of wider browser development and resulting in a load of their loyal user base defecting.
At least they're put power saving at the top of their list as Chrome is apparently so crap ... sorry? It's now based on the Chrome engine? Umm err ... well at least they must have polished around the edges to reduce power consumption ...
Opera was, but no longer is, a real challenge to the non-mobile market incumbents.
