I don't see any reason to maintan this mod anymore. 'cause you can use Custom Stuff 2 mod to add this feature in 2 strings. Custom Stuff 2 thread.
I'm allways using shears to speed up cutting trees, and always have a problem: "How can I use this stacks of leaves?". Too many of them, to use them for decoration. And I decide to burn them all. That's how my mod was burn.
Now, you can use leaves to smelting your ores or other stuff. They are will produce heat for 0.75 sec, that meen that you can smelt 4 items per stack of leaves.
