In 1.13 you can create datapacks. Datapacks are basically very simple mods the user doesn't need to install. They can add/edit crafting recipes, add advancements, add functions, add structures, edit loot tables and do some more things. This is great, but editing them is really tedious. Here is a screenshot of me editing the loot table of a cow so it drops more beef:
I was creating a datapack for my survival world, and I had an idea. What if it were easier to edit. That is why I came up with this idea.
There should be an in-game datapack editor.
On the start menu, there is a button that says "datapacks". Click on it, and you get this screen
In this, you can select a pack and edit it with a simple drag and drop interface. I don't have enough time to create those things in photoshop, but it would be something like this
but with a minecraft theme of course (pixel font and dirt background)
To add a crafting recipe you drag items onto a crafting grid and click "add to datapack"
To edit loot tables you add items and type how many it should drop.
This would make creating datapacks way easier and this might introduce many new people to modding.
