I love opera GX for everything besides this one thing. I use two monitors and when I have two windows open on each, I noticed it's way too awkward to drag one tab and combine it with another.
Sometimes if you don't get it just in the right spot, it opens a window with GX corner for some reason which is really annoying. I switched from Google Chrome after nearly a decade and Opera GX is better in almost every single way I can think of - besides this. Is there a way to change this in the settings somehow? If not, I'm wondering if anyone else has noticed this problem.
