@mopw69 maybe such "miracles" happen through a virtual machine. But you do not have to combine it. Just install the developer version on a pendrive or HDD/SSD as portable. Only, of course, indicate a different location than installing your stable Opera.

+1, they got away from the web-browser version, and went to a windows program. I'm sure there was a specific reason for it. But that might score against getting it into the sidebar of Opera. https://community.signalusers.org/t/google-to-retire-chrome-apps-what-will-be-with-signal-desktop/469/3

The search box (in the speed dial page) can be turned off; searching from the address bar can be set to one of the other pre-installed search engines. The only way to change the speed dial search to a different site is to convince the browser you are in a different country - and the choices available then may not be available in mainland China. (There are instructions for how to manually edit your location in the Frequently Asked Questions thread.)

@charlietm +1 to that

@ultrastriker Or do the same as Firefox's overflow menu.

I would totally love this. Skype would also be nice.

Almost free VPN or proxy are not safe. I stay with Opera just cause it has free offical vpn and it will more usefull when get 3 options : alway on, alway off, auto(only on when visit a site in list).

@azot In both light and dark theme, the active tab has a different color than inactive. However, Opera still has only two preset appearance settings to choose from. I appreciate the functionality of Opera, so I do not intend to change my browser. However, in this respect, the Vivaldi viewer has more settings - a lot of color settings of individual elements (creating your own theme in many respects) and even automatic switching between 2 themes based on the time. Opera could have similar settings, but no, not because it's hard to distinguish between active and inactive cards. Just because it has richer settings.
