Features:

 + An interface that can run multiple keybinds & commands in order (EG drop a held item with the vanilla Drop Item key, then log out. In minecraft, that very thing used to dupe items and blocks in 1.12.2 when timed correctly, even on servers with anti-cheat plugins!). Should have the ability to add configurable millisecond delays in-between the individual commands, EG drop your held item, wait 0.08 seconds, then log out
 + Middle click while your cursor is over a player's model or the nametag above their head to add or remove them to/from your friends list

Utilities:

 + Auto Drop - Automatically drops items specified by the player when they enter the player's inventory. Only includes low fertility soil by default, but more items can be added or removed
 + Auto Eat - Self-explanatory. Pairs especially well with baritone-like pathfinding (more info below)
 + Auto Knap - Automatically completes the knapping "minigame" for you
 + Auto Smith - Automatically completes the smithing "minigame" for you
 + Auto Tool - Automatically switches to the best tool for the block you're damaging, EG switches to holding an axe in your hotbar if you start punching a tree
 + Auto Type - Automatically types a configured message on a configurable timer
 + Auto Undress - The opposite of auto armor, this should automatically unequip armor after not taking damage for a configurable amount of time - 60 seconds by default

 + Baritone-Like Pathfinding - https://www.youtube.com/watch?v=5rJkQgBJldU&t=6s
 + Basefinder - Highlights player-made blocks such that they're visible through other blocks like dirt. Great for finding bases, even ones that are hidden underground, from a distance
 + Better Step - No more collision that kills your forward momentum every time you walk up a half block/slab or stair block
 + Bow Aimbot - Self-explanatory
 + Bread Crumbs - This should leave a visual trail of dots, dotted lines, or something similar as you walk around.

 + Chat Filter - Should have the following options:
 ** Censor Words: Censors Filtered Words and matching items to Filtered Regex to become asterisks.
 ** Remove Message: Removes entire message.
 ** Filtered Words: List of words to be filtered, separated by commas or line breaks.
 ** Filter Logged In/Out Messages
 ** Filtered Names: List of names to be filtered, separated by new lines.
Example:
    Filtered Names: Gamble
    Gamble 5819 typed: Rigged dice games! Lose your money today!
        If using the censored words setting: GAMBLE 5819: ******** **** ****** **** **** ***** *******
        If using the remove message setting: (The message does not appear in your chat whatsoever)

 + Flight - Ideally this shouldn't get you kicked from servers for using it. Configurable flight movement speed, 2x by default, max of 5x
 + High Jump - Multiplies the player's jump height by a configurable amount
 + Inventory+ - This game uses a configurable inventory system. Fresh players only have access to their hotbar while players wearing 4 backpacks have an additional 24 inventory slots to make use of. Maybe you could find a way to change this so that, with this hack enabled, players can give themselves a new number of inventory slots between 0 and 99
 + Item Saver - This should move items from your hotbar to your inventory, as long as there's space, when an item only has 1 durability remaining
 + Item Speed - Speeds up tool & weapon usage by a configurable percentage, max of 500%
 + Jesus - Lets the player walk on water

 + Kill Aura new/replaced configuration option, smart reach: the maximum distances at which different weapons can reach enemies aren't equal. Spears have a longer reach than longswords, and longswords have a longer reach than fists. With this configuration option, the configurable activation distance would either be replaced by or supplemented with a number that takes into account the differences in weapon reach.
 For example, setting it to 0.1 and holding a 2.5 reach sword would make kill aura activate when entities are within 2.4 blocks of the player, but that same 0.1 setting while holding a 4.5 reach spear would make kill aura activate when entities are within 4.4 blocks of the player.
 This would still interact normally with kill aura's configurable time range - EG 0.05 to 0.3 - that randomizes how many seconds a player or mob must be within the player's kill aura before automatically being attacked.

 + Ladder Speed - This should multiply the player's vertical movement speed by a configurable amount when climbing ladders.
 + Log Position - This should mark the block that players within render distance logged out at. This hack should have a checkbox that lets the user display or hide the nametag of the player who logged out above marked blocks
 + Mark Block - Marks a block with something simple like an X or O by looking at it and pressing a hotkey. Useful for quickly & easily marking paths. The color of the player's marks should be configurable
 + Movement Speed - Increases the player's movement speed by a configurable amount
 + No Armor Penalties - Removes all penalties (IE increased hunger, decreased movement speed, etc.) that come from wearing armor
 + No Fall Damage - Self-explanatory

 + No Map Bypass - Some servers disable players' maps. This hack should bypass that, allowing players to see their map and minimap again
 + No Slowdown - For things like flowing water, armor, webs, and other things that normally slow the player down
 + No Weather - Disables all weather effects
 + Parkour - This should make the player automatically jump whenever they reach the edge of a block.
 + Reach - Increases the player's reach by a configurable amount
 + Spider - Lets players climb up walls
 + Safe Walk - Prevents the player from accidentally walking/falling off the edge of any blocks. Players can still jump off of a block onto one that's higher or lower when this is enabled

 + Scaffold Walk - Automatically places the block in the player's hand underneath their feet when walking or jumping
 + Steal & Store - Adds buttons that automatically take all items from storage containers or dump all items from the player's inventory into the storage container until it's full, like so https://wiki.wurstclient.net/_media/update/wurst_7.0pre22.jpg
 + Time & Temperature - Constantly displays the time and temperature in an upper corner of the screen
 + Tunneler - Automatically mines the 2 blocks in front of the player at leg & head height, walks 1 block forward, and repeats indefinitely
 + Zoom - Zooms in. Configurable up to 20x
