And another post by me. Sorry, but I'm learning the new Opera version and maybe this can help some people. Pig Toolbox's gestures are still working, but you have to deactivate Wheel Gestures and Super Gestures. Super Drag can stay activated. The gestures do not work in internal pages anymore.
Opera's own mouse gestures also have to be deactivated, but since there are only a handful you are not really losing anything.
I use Opera 20. Not everything I look for is in the text I am reading. And the most aggravating detail about this design flaw is the new tab anyway. If you don't want to go to one of your Speed Dial pages or search, fullscreen mode is completely useless. You can't access your bookmarks quickly or use other search engines or enter an URL
I'll just add this to the list of features that have to be added again... It's not getting shorter...
