Currently, in the vanilla game, chiseling blocks is very time-consuming; if only there were a tool or function within the chisel itself to copy a chiseled block and paste it onto another block In this way, on vanilla servers, larger and more detailed constructions would be seen in less time.
The ways I can think of to implement this are the following:
1.- Place the chisel next to the chiseled block on the crafting table in your inventory.
2.- Add some kind of tool that allows you to copy your chiseled blocks
3.- Copying a block directly from the chisel interface
Adding these features would greatly facilitate the construction and detailing of large buildings.
