Simple Efficient Crafting is a simple mod which adds recipes to the crafting menus. These recipes are for creating multiples of an item. If you have 5 iron Ore, wouldn't it be great to simply select Iron Ingot 5 in order to craft 5 Iron Ingots from 5 Iron Ore at a time? I created recipes for multiples of 5, 10, 25, 100 and 250 for most ingots except Dwarven. Dwarven ingot recipes were added in multiples of 10.

This mod requires SkyrimSE and the Dragonborn DLC.

Simple Efficient Ore - Choose this option to install recipes for Ore. This includes 5x, 10x, 25x, 100x and 250x variants of Iron, Steel, Corundum, Ebony, Gold, Malachite, Orichalcum, Quick Silver, Moonstone, Stalhrim and Silver. It also includes a 10x variant of the Dwarven Scrap recipes. These recipes are not a cheat, except that they save you a lot of button clicking.

Simple Efficient Ores

• Iron Ingot in multiples of 5, 10, 25, 100, 250
• Corundum Ingot in multiples of 5, 10, 25, 100, 250
• Steel in multiples of 5, 10, 25, 100, 250
• Gold in multiples of 5, 10, 25, 100, 250
• Malachite in multiples of 5, 10, 25, 100, 250
• Orichalcum in multiples of 5, 10, 25, 100, 250
• Quick Silver in multiples of 5, 10, 25, 100, 250
• Silver in multiples of 5, 10, 25, 100, 250
• Moonstone in multiples of 5, 10, 25, 100, 250
• Multiple Dwarven Ingots in multiples of 10
  

Simple Efficient Tools - Choose this option to install recipes for lockpicks. Anyone with basic access to a steel and a grindstone and workbench would be able to fashion lockpicks. I feel this option actually adds realism to the game.
Simple Efficient Tools

• Lockpick in multiples of 5, 10 and 25.
  
  • Lockpicks are made 5 at a time using 1 ingot of steel
    

Simple Efficient Leather - Choose this option to install recipes for leathers. Due to the variance of the number of leathers produced from different hides, the math on this is not as straightforward. I included different multiples depending on the base production variable in the game.
Simple Efficient Leather

• Fox Pelt 1:1, multiples of 2, 5, 10
• Wolf Pelt 1:1, multiples of 2, 5, 10
• Deer Hide 1:2, multiples of 4, 10
• Cow Hide 1:3, multiples of 6, 15
• Bear Pelt 1:4, multiples of 8, 20
• Goat Hide 2:1, multiples of 2, 5
• Horse Hide 1:3, multiples of 6, 15
• Sabrecat 1:4, multiples of 8, 20
  

I have done nothing to adjust crafting skill point gains. If you use a mod which adds experience gain from smelting and tanning by using the recipes in this mod, you will not level your crafting as quickly as crafting items one by one. So technically, this is to your disadvantage.

Feel free to suggest other items you would like to see added in the comment section. As I have time, I will add them.
