Sadly the new Opera and me somehow didn't work out. We just didn't click. I just tried again since 12.17 is now showing an available update, but it still feels like a downgrade to me.
For Opera like feeling in a Chromium engine I am using the Japanese Browser Sleipnir 4. Tbh it feels a lot more like Opera than the new Opera. Sleipnir 6 is also nice and as actively developed as 4 but it does not have the Opera 12 feel to it.
I am sorry, but I guess I am so used to Opera 12 that I cannot adapt easily.
