For those who actually bought the pack - you can add the gif (or else) showcasing every skill in pack) You can do it even with already existed pack - just update it)
Kinda like this one: https://bdragon1727.itch.io/pixel-holy-spell-effect-32x32-pack-3 (top one)
So I can open Acid pack and found "showcase_all.gif" and see every spell in action for this pack. Right now if I open Acid pack I have 13 folders with separate sprites or spritesheet. It's a bit hard to find specifically looking spell in packs) Hope I explain this right.
Just as quality of life improvement)
