@flaviu2@gcg1000 I had the same problem with my VPN showing up. Turns out you can do this through editing the preferences file directly, just not through the UI. You need to find the preferences file and set "freedom.proxy_switcher.ui_visible" to "false"
I have installed version 137.0.6036.63, the bug is still here. When I noticed the bug I also did a ticket: BUG-29432 New island tab button is not dissapearing
Hope to be solved in the future, because is very easy to reproduce.

Yes, lets hope for that, teoretically, if you have a scroll point, even if you move it at the top the page, its possible to get back to that scroll position.
And would be even better to have a feedback from Opera team.
"Close tabs to the right"
This is happen even when you try to close tabs in the right hand of the current tab, being part of the same tab island. Seems very unstable ...
