SharePoint 2010 href link in Designer Workflow email

Came across a new way of doing something that used to be done in SharePoint 2007 by coding in HTML directly to the Workflow Send Email body.

In SP Designer 2007, it was common to simply add directly the HTML of an <a> into the email body.

Example :

http://mysite/Lists/mylist/EditForm.aspx?List=0f272aa3%2Ddde0%2D46e2%2Db26e%2D931ce98b3312&ID=[%mylist:ID%]&source=xxx

In SP Designer 2010, it took me while to realise this cannot be coded into and the Hyperlink StringBuilder button must be invoked to build this URL.

Got me for a while.
