I could be missing something really basic here, but I don't really understand the value of Essential graphics outside of creating a market to share/sell templates. A market like that is great and useful but it wasn't all I expected.

For context, I spend most of my time in UX design tools like Figma and Sketch. A powerful feature in these tools are Components (in Figma) and Symbols (in Sketch). They allow you to create reusable components that can be used throughout your file (called instances). These instances usually have a fair amount of customizing that you can apply to them. Also, when you adopt this component-based workflow, you have a single source of truth that you can go back and make any necessary modifications. These modifications happen in realtime. If you change the color of something, you see it happen in all of your instances right away. This allows for fast exploration, iteration and design-decision making. This is further enhanced if you nest components inside of other components.

So, when I first learned about Essential Graphics in Adobe's video apps, I assumed that it would be similar components/symbols in Figma, Sketch and other similar design tools—heck, even Illustrator has symbols pretty similar to this.

When you create an Essential Graphic (mogrt file, I guess?) you sort of get this functionality inside of Premiere—you create a template, then you bring it in to Premier and you can modify attributes and reuse it over and over. That's great. However, unless I'm doing something wrong, it doesn't seem like you can really use these Essential Graphics inside of After Effects! That seems like a big miss to me. When I create animated slide decks and video presentations in After Effects, there are tons of duplicated animations. Being able to create and reuse animations (components) like this would be super helpful. Make it once, duplicate it multiple times throughout your video. Now if you want to go back and tweak the timing of your animation, you should be able to just go back to the original, make your adjustments and bam—they are all updated! But I can't see any way of really using these inside After Effects, let alone quickly and easily updating them (see: https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/34908181-sync-and-update-mogrt-templates-when-changes-are).

So what am I missing?
