I'd have to say the ability to throw down a model that creates in hurry is one of the nicer features of this particular tool. The one thing I would like to see added (and still don't get why it is still not there) is the ability to show the relational lines going exactly to the field in the table object list to which they are related. Few tools there are indeed that have this, but those that do have had it for years... like MS Access... since the early '90s... along with the ability to print within the platform...
It seems that every ERD design/modelling tool has some missing feature somewhere.
At least the abilty to change fields, add relationships, and add tables directly in the designer has been nice.
Good opening tutorial video and audio presentational skills, Brian!
