Hey, every tileset and sprite has their name or general category in its file name. Icons are not named since I don't want to impose what they are. But most of them (if not all that are currently in the pack) are self explanatory and shouldn't be confusing to use or tell what they are.
In short: as of right now there is only a list for player animations on our community discord server but if you have any questions you can ask me or other community members and we'll help you out :)
