Let's add one more question - answer pair to the FAQ.
Q: Can I use color slides between the different states?
A: Yes, currently QSR 1.2 supports color slide with timeline animations. Transitions change the color instantly without color slide. You just need to specify the timeline start and end frame colors in addition to the state colors. Please see <Src>\QtSafeRenderer-1.2.0\tests\auto\integrationtest\testsources\TimelineTest.qml for details.
