Use a label tag around the “Urgent:” check box on the Create Request form. It allows for a larger clicking target of the form control. (I.e. you can then click the text “Urgent” and it will select the check box.)
This may not be a big deal once a user is trained or told about the urgent feature, but I almost missed it because I didn’t notice it up there.
I really like how it turns the “Request Details” header red. That is cool and useful!
