My projects are generally consists of schematic files and showing every instance in entity tree is not needed. Project size in number of classes is very big (about 510) , but ISE 7 synthesize (including bitfile generating) it in about 4 hours, in instances it is very very very big. It is enough to show only classes in entity tree. Besides this DRC check phase in ISE version greater then 7 is very slow. Computer seems like hangs. I didn't wait til the end of DRC check phase because it is too long. Can you make "showing every instance" in entity tree an option in later versions of ISE Project Navigator?
