Does it have the Notes feature? That's something I use a lot in Opera 12 and miss in other browsers. It saves me from keeping a lot of random .txt files in my Documents folder (which is virtually unusable thanks to all the games putting their save files there). I also don't like how tabs work in Chrome, as new ones open after the current one, instead of at the end of the list (this is annoying if you have like 5 tabs open and click a link on the 2nd), and using Ctrl+Tab to cycle through them moves in order instead of to the previous one (as Alt+Tab does with Windows applications).If you don't mind the Chromium engine itself, you might want to take a look at Vivaldi Browser. It's still Chromium-based, but it's made by some of the people that made the Presto Opera and is made under similar philosophy. I don't really like the engine myself, so I haven't used it and can't say if it's usable for everyday browsing yet, but it's worth at least checking out.
