Oh no
That's very important feature and I thought this flag will help me.
Well... thanks for your response. I guess I should install a few other browsers and try working with them.

Hi,
recently I discorvered "side-profiles" flag for Opera so I wanted to try it but... it doesn't work or I have no idea how to use it

I was following instructions from this post: https://forums.opera.com/topic/53153/how-to-set-up-multiple-profiles-in-opera-gx/6. I went to opera://flags/#side-profiles, activated side-profiles flag aaaand what now?
Maybe I'm just misunderstanding but I think that the button with options should appear near this flag right? It didn't appear so I went to opera://settings/side-profiles-settings and it seams that link doesn't exist. It took me to main opera settings. Searching there for "side profiles" returns no results

I'm on Windows 11 using Opera 89.0.4447.51

Any help would be appreciated
Thanks!
