We now have "Remove Unused References" (AWESOME FEATURE!!!!)... now, let's see "Remove Unused Entities" in the Aggregates! Real simple... right click the Aggregate, it inspects the chain of "what's actually used?" (same logic the compiler optimizer users) and dumps the Entities and the JOINs that are not actually used in the Aggregate to filter/display/output (in other words, the right side of any LEFT JOIN that is not filtered on, sorted on, or used on the screen/output/logic).
