Logpiles could use a bit of functionality. There's a couple different ways to do this:

1. Right click with flint and steel, and get a campfire. Simple, easy, gives you a reason to carry flint and steel while hiking. Downsides: You can now get campfires without having to craft sticks or get coal/charcoal, although IMO this is a positive change. (I'd also recommend making the logpile recipe shapeless, because I think it's silly that Steve needs a crafting table to make a campfire.)
2. Right click with coal or charcoal to get an unlit campfire. A slightly-more-involved version of the above, as the unlit campfire would then need to be lit with flint and steel. Has the downside of requiring 3 inventory slots (coal, logpile, flint/steel) instead of 2 (logpile and flint/steel).
3. Right click with sticks for a chance to get a lit campfire. Best used in conjunction with option 1, IMO. Upside: You can now craft a campfire using only materials you can find in the wild. Downside: Someone out there is going to complain even harder because now you don't need to use a flint and steel to light the campfire.
4. Breaking a logpile drops 3 logs instead of a logpile. This doesn't implement the logpile -> campfire process directly, but instead makes logpiles a storage block, enabling you to grab 3 logs for a campfire by simply breaking a logpile. Ideally, this would come with the ability to stack multiple logpiles in one block, making logpiles a bit more convenient as a storage medium.
