Inside the reference viewer there is an graphic display of all references. Right now it is possible to assign different colors to the different reference types by clicking the icons next to the check box.
What does not work so well right now:
The coloring information that has been assigned to the reference types will be lost after the next Creo start. In the new session all colors are turned to gray. They must be defined one by one again within each Creo session.
What would be an improvement:
It would be an improvement if these colors could be saved as system default and always available when starting a new Creo session.
