I'm on Linux and on Linux there's a problem with the way 'right-clicking' works:
When a mouse-gesture extension is added to Opera, Linux users have to double-right-click to make the context menu appear. This 'bug' is annoying as hell.
Except when using Opera's own mouse gestures, then a 'normal' right-click opens the context menu and mouse gestures work. BUT... Opera's own mouse gestures are laughable at best, there are only 5 or so.
Opera would be my goto browser (it is on mobile), but I can't use it because of lack of mouse gesture support. Double-right-clicking is not an option either.
Please add more gestures, like re-open closed tab, switch to tab on the right / left, etc. or make at least the ones present customizable.
(I'm wondering, is anybody from the Opera team actually reading these topics / suggestions?)
