The animation window has some weird indentation rules. I'm assuming that it's indenting based on how many levels deep the property is relative to the top-level object. But when you're not including all properties of an object, it looks very strange. For example: I assume there's probably nothing I can do to reclaim some of that space, all the wasted indentation, but maybe you could look into whether there's a more sensible approach here? Maybe even an option to toggle on/off the hidden ancestor objects that these are being indented under?
