CustomPress: Custom Field Type Suggestion

After using the CustomPress plugin, I would like to suggest the following custom field types be added:

Numerical - This would limit the user from entering text when numbers are ideal.
- Support of 2 decimal places would be nice too

Multiple field types within same Custom Field Set(?) - Allowing user to enter two or more data entries.
Example:
Custom Fields > Add Custom Field >
Field Title: Sample1
> Field Type A (textbox, multitext, dropdown, etc..)
> Field Type B (textbox, multitext, dropdown, etc..)
> + Add another Field Type
