I don't get why they aren't just doing this already, this thread alone has 44.9k views (at the moment of posting this) so probably a good percentual of these people want/need/could use Opera GX on linux. Maybe the Opera GX devs could be already trying to do this, and maybe working on a beta version, but here's my message to the Opera GX staff, team, devs, etc.:
"Please, if you are bored of seeing all these replies under this thread and others, just tell us that there's something going on, some testing, something that will maybe, one day, come to life and become a finalized version of this browser. If there isn't something actually going on, you (the team, etc.) can try to make it work and if there's no way it's gonna work, then just stop and tell us. But, please, don't leave the silence be like it is. Just talk and tell the crowd (which is probably a good part of your everyday users and fanbase that are switching to linux or already use it for its gaming performance, as said in my previous reply) what you have to tell. We will all appreciate it, good or bad. Thanks for your support."
