Great large and small details and ideas

-Make glass' outline texture disappear on the side that is connected to another glass pane/block

-Make minecarts faster

-Scale monster's vitality/strength to how many achievements they have that involve combat (for example, after the "Suit Up" achievement, monsters hit stronger and become even harder to beat after the "Cover Me in Diamonds" achievement.

-I'm on my knees BEGGING for multiplayer worlds to cost less. The sales would go so far through the roof that even with decreased prices you'd still make more money

-Make the Enderdragon harder to beat somehow. Maybe after clearing out all of the crystals, it starts swooping down to hit the player, dealing less knockback than normal hits, but it doesn't stop it's course down to the player no matter what. You'd need an enderpearl to avoid it.

-Give woodland mansions a boss. I don't care what it is (ahem Illusioner ahem), but I feel like they aren't too challenging to take down and they don't give too much loot.

-Please make the chances of an evoker dropping a totem of undying lower, it makes minecraft a bit too easy when you can farm them.

-I don't know if you have it planned for a later update, but please make use of the portal in Ancient Cities. Maybe to a dimension that isn't required to beat the game, but has new mobs and is incredibly late game. Like, you need good stuff to survive but it gives you amazing prizes in return.

Thank you for hearing me out.
