I think that there should be an option to craft in creative mode by going to survival inv. in creative mode. In the inventory there should be a crafting-bench style grid in which you can craft. I also think that there should be an Axe enchantment only obtainable through gold axes or enchanted books called "Timber". It would make the axe sort of like terraria in the sense that when you break the bottom wood the whole tree comes down. In this case, when you break the bottom wood block, the whole log is dropped. This is also like the chainsaw in tekkit.
I played on a server with it once and Oh man do I miss it.
So Support for the Timber Enchantment.
Also, this is a wishlist.
No, you can't.
