make the two main sections of the animation controls more distinct.
Apart from the blue/orange coloration of the lower portion with the scrubber whatnot, there isn't a sufficient degree of separation between it and the timeline atop it. Yes, once you know how the three work together (indicator, scrubby thing, zoom) it's workable, but it's not something you can just glance at and just know what you're seeing. IMO, if, in between the two controls, there was a "bolder" separator, even a few pixels, to let the user know "these serve entirely unique purposes" - it could only be good. In general though, Having three (four counting the menu) controls for an animation will be overwhelming and offputting to prior wundermap users.
Thanks for bringing this up — it's exactly what I've been hoping we can do to clarify the relationship between the two time bars.
