One situation in which this is obvious is when you're adding and updating a user's shopping information, such as name and address. And once a page is created, changing individual attributes for each column of a query result requires selecting and changing each field individually. A multiselect option would be more desirable. If you need more flexible order completion, however, you'll need to develop an expanded state mechanism. Taxes, shipping, and volume discount components depend entirely on your external database structures for each, although TaxWare integration is supported.
Development can thus proceed without affecting the live system.
Unfortunately, the design tool is single-user, so you can't use it with larger projects where a collaborative mechanism is necessary. A helpful feature of the statistics module is support for click-stream analysis, which tracks how a buyer traverses your commerce site so you can improve navigation or offer sale items where most appropriate. Any field in any database can also be counted for sophisticated statistical reporting.
