Yeah, me too. I've been using Vivaldi the last couple of months and not only did this fix the problems I had with Opera, but the number of options you have in Vivaldi compared to Opera is just mind-boggling.
At this point, I don't think I'm ever going back to Opera. They convinced me with all that talk about multi-threading and stuff, but it just wasn't worth it. The thing I regret most, isn't going all-in myself, but the fact that I recommended Opera to a lot of people - they must think I'm an idiot.
