What if 2 got color "blue", 1 got color "red" and 3 got color "green" and I want to change color of all to "white"? Option dialogs with grayed fields make mum's oldest angry like chief rain-in-face :-) (and the dialog would be a useless feature. Why making it possible to edit multiple objects and then limit it again)and if objects originally have different values for a property, the original value shown in the dialog should be greyed (like other office tools do)
