Abandoned Mine Shafts

So I think it's time the Abandoned Mine Shafts get an update.

I believe that coal deposits Should become more common (because it's a mine shaft LOL).

Also mine shafts should have more vines/ flora to make it look old and reclaimed by nature

And also PLEASE give better stuff in the minecart chests like

( iron, coal, gunpowder, pickaxes and on a rare occasion golden apple's and diamonds

Next Make abandoned mine shaft's spawn closer to Villages and have cartographer's sell maps to locate a rare version of the mine shaft that still has some of it's buildings intact but is infested by skeletons and has double the risks (but a higher rewards)   

Next your going to need something to combat the skeletons so introducing the monster slayer enchantment to get this rare enchantment you first have to locate a blacksmith in a village and trade a shapness 1 enchantment and a sunflower to use the enchantment your going to need 1 experience level or more

Finally update the mine shaft to look abandoned because IDK about you but they don't look too abandoned to me
