Limit the number of characters
limit the number of characters you can add on the text field and text area field. So for example if I wanted to link a text field with twitter, I would want to limit the text to 150 characters or how ever many characters twitter can take.

We have a use case for similar field validation for eg bank account number, where we want max 8 characters.

The other good thing to this will be a character countdown feature if character limit is set.
