Colored Frames Rows in Animation Window

Hi there!
I've noticed that when animating a large number of objects and/or a bunch of their properties, the animation window can get very messy and honestly my eyes are sore after trying to distinguish frames from different objects and properties.

I saw in the asset store there are custom Hierarchy "colorizers", like this: https://assetstore.unity.com/packages/tools/utilities/hierarchy-plus-97887 and this: https://assetstore.unity.com/packages/tools/utilities/rainbow-hierarchy-106670

I was wondering if there's something like that for the animation window. And if not, I think this is something Unity could improve on! I'm a regular After Effects user and their "nested", colored layers in the timeline work really well to avoid confusion.

I've attached a quickly photoshoped version of what I have in mind

Thanks for your time!
