A keybind to place a torch for either the inventory or from the torch holder item.
Default keybind is U, I suggest chaging it to as an example Mouse buttton 5 if your mouse has such a key
The normal mining flow for me as I am old school is to have my torches in slot 3 besides my pickaxe and then every free blocks I would switch to the torches and place one and then select the pickaxe to continue.
This loop of switching is what this mod eliminates as now you just push a button to place a torch instead.
Also it adds a Curios compatible item to hold the torches which the keybind then will take the torches from.
