Properties: If only one object type was selected, the Properties page for that object type now displays. If more than one object type is selected, the main properties page displays.
I don't think it is a good idea. I'm working on a file with grouped TEXT: let's say - 10 groups with over 100 items each. Activating them takes sooo much time as display page goes through all individual properties.
Skip it or leave it as an option and definitely not as default.
