A lot of my friends have moved to another browsers due to sidebar absent. We can't understand why at previous versions of Opera this deal was present, and at new is absent.

No one understands that, but they spend / waste time with Opera Neon...
Nice? Rigth, nothing else...

Is Jon Stephenson von Tetzchner blocked some features to be ported to Opera Blink?

Vivaldi has sidebar and a lot of Opera Presto features, so it can be done...

It's Opera want us to foget?
It's Opera shame himself of the bad move and canno't make peace and surprise again?
