Please don't use this mod anymore as i stopped developing this mod.

You hate to go to your inventory and put the last block you placed into your hotbar? Or you're too lazy to middle mouse click to make it semi-automatic? Or you're just too slow while flying and building fast? Then this mod's for you.

Selects the last placed block and just does the middle mouse click by itself using events. As those events are client-sided you don't need this mod on the server. It does work on vanilla servers too. :)

Available for Fabric, Forge and NeoForge.
