If you ship the new UI like it currently is, you are doing a massive disservice to every Opera user.
The most basic of functionality is missing and it's unnacceptable:
- you can no longer drag the mouse cursor to the very top edge of the screen and select a tab (or middle click a tab to close it)
- you can no longer drag the mouse cursor to the very top left corner and select the Opera menu button
- you can no longer drag the mouse cursor to the very left edge of the screen and select the scrollbar
This is basic muscle memory that every user has because every other browser has this. What you are doing is borderline criminal.
I am a big Opera user and supporter, but if Opera 100 ships like this in Stable, I will uninstall Opera and tell everyone that I previously told them to use Opera to uninstall it too.
