Some examples need more work i think

"Database backup" has circular arrow spinning backwards

"Earth" shows lines being drawn -- instead i expected it to show an abstract spin of the globe

"Droplet" animates the outline draw. Expected a droplet that starts small and descends to become full size.

Same with "flame" -- should ideally be an animated flame licking up / whisps

"Copy" and "File Stack" -- the animation shown should ideally be reversed i think

"Git-branch" -- animation is wrong, doesn't show branching -- just drawing nodes and lines.

"Hand-grab" -- should start with open palm and then the grab.

Same with "hand-fist"

Many animations are simple zoom/enlarge - like those on right angle arrows are not serving a purpose

Others just draw the SVG path or wiggle/bounce a bit.

If I were the creator here I might differentiate this into two buckets: custom animation or not. And then allow the generic animations to be applied to any of them.

When I hit back and get returned here when I wanted to check out other icons made me not go back to check out others.
