Can you please put in the ability to highlight layers with different colors. It's a sea of gray in the interface, which makes it easy to add a keyframe to a particular layer when you meant to add it to a layer just above it. This is especially true if you're trying to make several layers that need to be moved together but are separated in the stacking order by several other layers. So, to remind oneself that several layers are related, it'd be great to be able to color all of them green or red, as in After Effects. I don't know how hard this is to engineer but it seems to me to be something absolutely necessary immediately.
