Password field and tooltips

Thank you for this awesome plugin! I don’t know why I haven’t found it sooner.

Do you think you could add a password field type? So when people are ordering something like a script install service and they have to add a password it doesn’t get displayed anywhere except to me as an admin.

Also can you add a way to display descriptions below the input or in a tooltip beside them or something? Similar to how the options in WooCommerce have little ? icons with tooltips. The placeholders can only fit so much text.

Thanks!
