As I stated in my initial report, if the tab bar is full, there is no convenient way to move the browser window. I have about 4 pixels of leeway to click for dragging.
Also there is the annoyance of information hiding. When you stuff all the menus away into subcategories of one menu bar it’s very frustrating digging around for something that used to be right there in front of me. Information hiding is fine when you’re on a handheld, but it’s pointless on desktop. I understand the modern design philosophy of making every platform look identical but it really is killing usability of non-mobile platforms.
But I have reverted to the older version of the browser so I’ve avoided those headaches for now.
