With the improvement of multiple windows per user, a particular use case has been users opening several tabs with different workflows shown within. In this context it would be of use to be able to see what area that tab/window is within.
"OpenVPMS - Main Clinic - [Customer details]"
Workflow - Schedules - [Customer details]"
The OpenVPMS icon should be enough to indicate to user that this is an OpenVPMS window (plus the recognisable text).
