It can be hard to select the right association when there are a lot of associations on an entity. The Find usage function on an association is very useful but when there are a lot of association this is hard to do. However, the association can be selected easily from the property page of the entity.
Hence it would be nice if the Find usage function is available from the property page of an entity.
Totally agree, this can rather quickly become a problem with small entities with several cross module associations.
