Thanks, I appreciate that. I think it's more likely that I slipped through the gaps a bit because I've been participating on this forum long before we had these voting mechanics and I haven't been very active once Opera moved to this version.
As far as site settings - it's exactly the same as Chrome. Click on the lock or globe icon in the address bar then select Site settings in the pop-up. You should have guessed that one.
Well, I don't use Chrome and once again it's not as obvious as you say. See: most sites use HTTPS these days which means that the globe is usually a lock. As such my assumption was to find more information regarding the certificate when I clicked on the lock, not extra stuff such as site information. It seems a bit illogical to me.
We all approach these things differently of course, but more than often features are picked up differently by newcomers than veterans.
Thanks for the feedback!
