Clarify prop mapping textfield option

Problem/Motivation

While reviewing the third part of our DB/Canvas comparison article series I came across a note from Pierre to clarify the recommended usage of the Textfield option in the prop mappings:

• Add a component
• Go to prop settings in right sidebar
• Open Dropdown
• Select Textfield

It's the only place where DB let's us enter data directly and it's limited to 128 characters. Can you clarify the recommended usage of this?
