This list is mainly so that I don't forget which changes and ideas I want to implement soon. Comments and discussions are welcome though :)

In no particular order:

• Separate common from NeoForge-specific code to facilitate the Fabric port
• Update to Minecraft 1.21.4 (or 1.22 when it comes out)
• Add more customizability via data packs, configs or events
• Update to Minecraft 1.20.x (with NeoForge)
• Add config options for disabling some of the Ceremonies (Rain/Drought) (#79)
• Add config option for adding custom wood types (#122)
• Make selecting instruments prefer Totem Bases that are already in selection mode (to make the selection more intuitive when multiple Totem Poles are placed near each other)
• Add Red Cedar hanging signs (to the 1.20.4 version)
• Improve the music particles (e.g. make them move through the air from source to destination, make them different colors) (postponed)
• Rework the Medicine Bag (maybe make it drain Melody from Totem Poles for charging) (postponed)
• Implement the reworked Totem Pole models made by @VincentLongiug (#108) (postponed)
