Enchanting Table Improvement

As of right now, the enchanting table is not really useful since it's easier to get enchantments from villagers or treasures, so I have a few ideas to make it better:

. First, you shouldn't need so much level to get better enchantments because it's really hard to get good enchantments, so you have to try a few times before getting something good, which costs a lot of XP.

. Second, you should have more options of enchantments to choose, like having 2 lvl 1 and lvl 2 enchantments (a 2x2) and having 1 more of each every 5 bookshelves you place around to a max of 15 (a 5x5, with 5 options of enchantments for each one of the 5 levels). This would make the enchanting table more useful since you can actually choose what you want and it's not entirely luck based.

. And lastly, maybe some way of giving more enchantability to books would be cool, like adding gold to make a book with golden corners and/or edges like it's done sometimes in real life so we can have better enchantments.

All these changes would also make the anvil, lapis and books more useful and could even make mending less broken since enchanting everything again wouldn't be a big problem, encouraging players to make more tools instead of waiting to have mending and never grind again.
