I know this may not seem like a problem to many but I constantly misclick on the menu button intending to open up the first tab I have opened. Opera is too unforgiving everytime I accidentally do this. Clicking the area where the first tab is does nothing as it is now covered by the menu overlay. What I do then is to click outside the menu area to close it and hope to not misclick this time.
I have since pinned the sidebar as it helps a lot missing the menu button now as it is not that wide anymore, but clicking the menu button still blocks the first tab that you have which I think shouldn't be the case.
Am I missing something though? Is there a way to move the menu button?
I made a mockup trying to solve this problem: http://i.imgur.com/csfGv1W.jpg
