Let me now add, since it's been awhile, that I now have Zen browser with transparency loaded and looking beautiful but I still can't get OperaGX or, now, Opera Air. Like, that one is built on Opera One. There is no legit reasoning on this. Yeah, I've made Vivaldi "look" like GX, but it's not the same. No pinboards, sync is out of whack, etc. And yes, everyone
That's what they go by.
