When a user drags an attribute or measure from a table onto the canvas, it would be beneficial to highlight all related tables based on an active relationship. The highlight might occur the same way as it does today to indicate which table an attribute came from. The point is that as Developers, we're creating a matrix to let users know where tables are related in large models. If we had this feature, we could train them to look for related tables and avoid dragging in data that is unrelated and produces erroneous results.
