This mod lets you enable which block should fall down like the sand block.
By default it only applies on the logs and leaves blocks.
You can change this by editing the json file in the data -> tags folders in the mods jar. (resource pack or by just opening the jar and editing the falling_down.json file)
Example to add another tag: #minecraft:logs
Example to add just a block: minecraft:dirt
Warning!
If you add blocks like stone, dirt into the file then that can slow down the game sometimes.
Server needs the file too in multiplayer.
