I am adding about 20 new fields to an entity. Would be nice if I could do that easily in one dialogue instead of one at a time (PHPmyAdmin-style). Now I have to hit the "+column" icon and do it one field at a time. (Unless I'm missing something.)
Something to consider especially when custom entity creation is rolled out.
