Mods that help you see or visualize data like minihud allow you to see light levels on all blocks around you. These only help make data you already know easier to see or get!
https://www.curseforge.com/minecraft/mc-mods/modmenu <- Configure your mods easier.
https://www.curseforge.com/minecraft/mc-mods/litematica <- Paste ghost schematics down and build buildings from your creative world much easier! It will also show you a material list.
https://www.curseforge.com/minecraft/mc-mods/betterf3 <- requires a lot of configurating but makes F3 just that much better as well.
https://www.curseforge.com/minecraft/mc-mods/minihud <- Minihud. Allows you to make a mini F3 mode AND easily access more information like seeing light levels on blocks or Beacon range. Will require configurating
https://www.curseforge.com/minecraft/mc-mods/free-cam <- Be very careful with how you use this one. Use this only to see your builds from a different angle or help spawn proof a farm. Using this to E.G. find caves and mine OR otherwise look for resources will get you banned.
https://www.curseforge.com/minecraft/mc-mods/beenfo <- Bee hive info, the servers have the plugin installed!
https://modrinth.com/mod/advancementinfo/version/1.19.1-fabric0.58.5-1.3.1 <- Bigger GUI and it shows which requirements you've done/haven't done
https://modrinth.com/mod/cleardespawn/versions <- Will flash items that are about to despawn. The faster it flashes, the closer it is to despawn.
