In addition to seeing the jobs your are associated to, you can search for any job in the system using the spy glass in the upper right of the Jobs screen.
Your choices are:
All - search by part of the customer name, Job ID, City Name, ID3 or ID4 (per the label you gave them) job description, site name, or job address.
Predefined - there is a list of Chronicle's predefined searches for you to use and they can be sorted by received date, job number, name, or be ascending or descending.
Saved - lists off the customer searches you have created from the desktop on the Jobs tab.
Custom - you can create a customer search on the app (but it can not yet be saved from the app.
This gives you the ability to find say the jobs that have unsold departments.
