In all previous versions of CRM field description served no purpose except reminding customizers what the field is about or serving as part of project documentation. CRM 2013 now displays the field description as a tooltip for the field label making it the first port of call to improve form usability and to provide instant help to the end users. HTML is not supported but new lines are honored.

So now is a good time to remove that “Our CEO is an idiot” description – who knows, his mouse just might come to the rest on that label.
