https://aescripts.com/declutter/
A fast After Effects extension that automatically cleans your messy project panel.

Declutter is an After Effects extension created to organize your project assets into predefined folder structures. You can create and store your own folder structures with their own names, suited to different types of projects or needs. Within each structure, you can customize the parent folders, child folders, folder labels and names, and what type of assets they're going to store. You can be as perfectionist as you want!
After you've created your folder structure just save it for later use. Choose a structure from the list and within a few seconds you'll get a clean and beautifully organized project panel.
