@granddaddyopera The answer for the title is no.
Opera GX came from standard Opera, so it should have everything that the standard version has. With that said, they will remove things only for a reason

My guess is because of the design. They might bring it back in the future, hopefully, with an option to enable/disable it (I really prefer a single sidebar but having more options is always better).

Also, everything you could do to request this was already made with your post, because there's no dedicated "Opera GX Feature request" forum, so you must have faith that some dev will read this topic.

I have this same problem.
I've tested in the standard Opera, and the problem only happens with dark theme.
This is clearly something the devs forgot about, just like trying to rebind any of those keys would crash Opera GX.
PS: the link for this page is "opera://extensions/shortcuts"

@dalto O Opera não suporta essa funcionalidade, porém o que você pode fazer é arrastar diretamente para dentro da janela do Photoshop, ai funciona sem problemas

• The setting "Disable tab bar's top spacing when window is maximized" doesn't work, even after rebooting the browser. Link to setting: opera://settings/userInterface. This happens in both GX and normal Opera.

• In the "Instant Search", depending on which color are you using, the highlighted result has either a dark text or light text to have a better legibility, but only the result itself, not the "- Google Search" text and the one in the active button. Color used: "Level Up green".
  

• The extension's shortcuts page has unreadable text. Link to page: opera://extensions/shortcuts. It occurs in GX as well as standard Opera (if using the "Dark" theme).
  

Also, in that same page there's a minor issue, where there's a transparent "Menu" button in the top left corner, in the left of "Extensions", it is clickable, but do nothing. So I guess it shouldn't be there, right? It's present in GX and normal Opera.

Hi, found a bug in Opera GX that makes the browser close and re-launch. The steps to reproduce it is simple:

• Open a private window
• Go to a web page that you can download something
• Open dev tools, not in docked mode but in separated window mode
• Start downloading something, and before it finishes, you must click on the close button of the private window.

The normal behavior should be displayed a warning about the non-finished download, and if the user click "yes", then the window closes, but what is happening is that it closes before you even interact with the dialog.
I've tested it with docked dev tools, and it didn't happen.
BTW, this bug is also present in the standard Opera.

Tech info:
OS: Windows 10 Pro x64 - Version 1903 - Build 18362.295
Opera GX version: LVL1 (core: 63.0.3368.55362)
Opera version: 63.0.3368.94

I would like GX to support both Lightsync (from Logitech) and iCUE (Corsair).
Also, you could use these services in a mixed way, because I believe I'm not the only one who has, for example, an RGB keyboard of one brand, and an RGB mouse of another.

That's it, thanks.

@abnerfrei About the Netflix one, it should show the video pop-up button, but there's a bug, present even on the Opera standard.
With Prime video, I guess it also could be affected by this bug (maybe is something related to Widevine DRM plugin)

@vicarious I tested this here with "Start from the beginning with start page" and "Open a specific page or a page group", and in both ways, closing the window on the secondary screen didn't close the one on my main monitor.

Did you have the "GX Corner on the sidebar" enabled?

I recently changed the browser color to a custom yellow, and came across a problem with instant search where the color of the selected line is very light.
I wish there was a way to change the color of this element only, or for the browser itself to adjust automatically.

I tested several colors, and apparently any light color other than the default will present this problem.

With the standard color

With the "level up green"

With a custom yellow
