One thing that is frustrating is the lack of a combination crafting menu. This is mainly caused by the crafting interface in the Pocket Edition being a menu that auto-draws the crafting recipes. This causes the following features to be unavailable without damaging an Anvil:
*Scaling down a map (Zooming out a map)
*Copying a map
*Combination Repair (Take 2 damaged tools, combine them in your crafting interface, combining the remaining durability of both tools +%10 bonus)
What is so silly about this is this problem could easily be solved 2 ways:
Create a new crafting recipe for each combination crafting item.
Pros: No new GUI needs to be coded.
Cons: Duplicate crafting recipes can confuse the end-user, unable to select the exact two tools you wish to combine.
If the player has 2 identical tools (enchanted or not) it would display another crafting recipe for the tool, but the crafting components are the two damaged tools.
Option 2: (The best option)
Crate a new tab- Combination Crafting Tab
Pros:Near-Identical crafting to the Windows 10 version (of which is identical to the Pocket Edition, it's just using a different interface. Don't believe me? Install MC Master and go to options, then tick Windows 10 Interface)
The Icon for the Tab could be an Anvil.
Clicking the tab would:
*In the Inventory Menu: Open a 2x2 crafting grid at the top, and the player's inventory at the bottom. The player then, much like a furnace, selects a space, then selects an item from their inventory. After the two items to combine are chosen, clicking the "result" window will combine-craft the two items.
*When interacting with a crafting table:The Combination Crafting Tab can be tapped, after which, a 3x3 crafting grid is shown in place of the 2x2 one. The interface layout is essentially the same. Crafting grid on the top portion, result on the right, inventory on the bottom half. Scrollbars for the inventory if necessary. (If the GUI Scale is turned up, for example)
BONUS Option 3:
Have the Combination Crafting menu I described, REPLACE the current crafting menu. A book icon can be on the top-right of the crafting menu that would open the one-click crafting interface that is currently present.
Now if Mojang NEVER implements this, when they add modding to MC:PE, you can bet your backside the first mod I'll make is the Combination Crafting Menu. NO MORE DAMAGING ANVILS FOR CRAFTING MAPS! NO MORE POTENTIALLY WASTED DURABILITY ON TOOLS!
