Hi Charlie,
A good additional feature for CS Forms would be the ability to add a description to any field. This would be a text field to appear below the input field, allowing a fuller description for the field. Just like the existing Label field, this could be toggled on or off.
I am currently getting around this by using a standard text field with negative margin to bring it close to the input field, but I reckon a selectable description input would be a better idea!
Thanks,
Christopher
