Does this plugin allow the use of Tooltips?

For extra fields you can add them with javascript onfocus.

Example: you have a phone field and want to show an example entry of (xxx)xxx-xxxx and when they click the field it disappears.

On the form edit page go to the extra field you have for Phone and add a “Default value:” (xxx)xxx-xxxx
Next, add this to the “Attributes:”
onfocus="if(this.value=='(xxx)xxx-xxxx')this.value='';" onblur="if(this.value=='')this.value='(xxx)xxx-xxxx';"

When version 4.0 comes out, you can do this to any field.
