Wouldn’t a date & time widget that can be used on the home screen and in reporting.
Use case: I have built a dashboard for myself with an overview of my tasks (by custom field), tasks I have completed today and over time, etc. It helps me keep track of my work and acts as a motivator.
I use clocktab.com to display date & time in a different window. A new widget would avoid an extra open tab?
