The only thing left to solidify Opera as my go-to browser for everything would be front-end profiles with usability in mind. I know it's the same tired banner that everyone's likely sick of by now - "you can make multiple profiles by making desktop links," "use this extension that you need to figure out yourself," etc.
But come on. How can the most requested feature of this browser somehow not be already in one of these updates or in development? And if it is in development, could the Opera team please, pretty please with a cherry on top, send us a message? A simple Tweet is all I ask. Just "hey, we have heard all of you, for the past couple of years we have been around. It's coming." That alone would do wonders for this browser, and I would finally be able to ditch Chrome once and for all.
