Why is the Stack By ability missing in Windows 7 RC? It was one of the most useful, if unknown, features in Vista- one of the reasons I actually switchedto Vista at work, in fact. Sort By/Group By don't provide the same functionality and are not nearly as useful. Why would they take a feature-complete, community applauded option out of the OS? Is there another way to enable this via a registry entry or other tweak, at least?

ABSOLUTELY agree. Stack By basically automatically creates virtual folders that you have to manually create one by one with sort by / group by. Libraries is like stack by except LIMITED to predefined attributes like tags, month.
