I would like the ability to create data entry forms for MapInfo, I imagine the feature would allow you to setup and associate a form with a particular table then whenever a new object is added to that table the user would get a form popup that would allow the user to enter the attributes for that record.
I would like the form to be as user-friendly as possible so it would require a number of different input types including textbox, preconfigured dropdown, dynamic dropdown, textbox with auto completion based on values already entered, calendar widget, ect.
The main reason I think this would be of great benefit is it would allow you to standardise the data entered into a table as well as reducing the complexity for users of correctly attributing data.
A few other things would need to be thought though such as data validation, reuse of forms across multiple tables, permanent form association vs. workspace based form association.
Please add comments if you think there is anything I missed.
