Admittedly, my company has a large quantity of records in several modules, but the amount of time it takes to create new fields in Studio is kind of nuts. The mechanism you use to create fields is not scalable. In large modules, this can mean 10, 15, 20 minutes of waiting--if it works at all. In our largest module, the process sometimes times out and I have to start from scratch and wait another large chunk of time for the field to hopefully create. As an admin, this is incredibly frustrating and inefficient.
