I want to collect additional information from guests that could help us provide a better guest experience and more targeted marketing efforts. Allowing us to create specific formatted custom fields could greatly support this.
For example, instead of just plain or RTF, I'd like to specify a standard date format, MM/DD/YYYY, for their birthday or anniversary. I could also see value in checkboxes (multi-selection), radial buttons (single selection), character validation (e.g., requiring numeric vs. alpha), and related fields such as additional contact and connecting an address, email, and phone number linked to that person.
I'm probably not considering other helpful field types, but you get the idea. Ultimately, I'm unclear as to why we're currently limited to plain or rich text formats.
