Show [Time to Resolve] progress bar or percent value in planner view

Referring to planner (this one showing on front page) - when there is a need to change the term of a task for another day or two, there is no information how much time technician have before he exceed SLA - sure, he could get directly into ticket to know that or use ticket list, but still..

A little progress bar/icon/xx% status that will show Time to Resolve as option to enable/disable in this view would be very usefull 

Image to better explain my suggestion:
