More Field Types
More types of fields with richer options must be available.
If Forms is meant to compete with market leaders in this sector, it cannot offer just 4 types of fields it currently offers. See attached screen shots of how many types of field other services are offering.
Also, you need richer options. For example: you cannot offer only one type of date formatting. We use dd/mm/yyyy in Europe. Americans use the mm/dd/yyyy. The form creator must be able to define the desired format.
In general, we need more types of fields and more advanced control options for each type of field.

Agreed on the date formatting. This is very important indeed. For most of the world 6/7/2018 is 6th June 2018.
