Offhand Overhaul is a mod that fixes the offhand slot. It is fully configurable, allowing you to specify what happens when right-clicking with a block in your offhand while not sneaking, and sneaking - no more accidentally placing torches all over the ground.
To get started, install the mod and use ModMenu to edit the configuration to your liking.
