Indicators for Changing Keyframes

When you add keyframes that changes color of a shape, we get a small preview right in the timeline, of the spectrum of changing colors adjacent to the keyframes. This feature is hugely helpful when animating colors.

Now I think all keyframe data should come with the same clarity. While looking at the timeline itself one should understand where are the portions where the values change (of any property), and where is it held static, in between keyframes. This, without having to move the playhead up to the keyframes looking at the property value under its label. Dots (resembling the ones that go in between postion anchors) that appear in between keyframes on the timeline panel, with a frequency guided by the rate of change can be a great solution. I've added an image to make my concept more clear.
