If you're like me, you find that After Effects' standard Ease in, Ease out, Easy ease options get pretty stale to look at. If you like to manually adjust your eases with the graph editor, this tool is for you! Use EaseCopy to copy those carefully-adjusted eases to your other keyframes. Get started right away with a very quick and simple UI. It's super compact so you can have it docked at all times, since you'll find yourself tapping those buttons quite frequently.
