Meanwhile, you are trying very hard to convince other's that single clicking has only adventages. But you fail to mention my biggest concern anywhere. Which is how are you supposed to select items? Do you always have to click-drag a box around items you want to select? If so, do you agree that there is the chance to accidentally click on items when you meant to click-drag a box to select? It is harder to accidentally double click. Double clicking is very distinct. Best regards, -Stephan
