What is the difference between the two buttons? I only see that everything is checked with button 2 and nothing but the main is checked with button 1..
Is that the only difference? or am I missing something else?
I use button 2 and just remove what I don't want, and it seems with button 2 that I should check off what I do want. Are these two options like the ole question "Is the jar half full or half empty"? or depending on how lazy you are which shall I choose, "To check or to uncheck"?
