Shows current armour durability and percentages.
Warns you when there is a block close above your head - so you know a jump will hit it before it does.
When your arrow hits a player, a chat line says who and from how far: "Bow hit Name from 23.4 blocks".
Tracks your current hit streak.
Tracks left and right click speed with rolling updates.
Renders a custom Sour Client crosshair.
In a fight, how much health you are up or down on the player you are fighting: +4 when you have 6 hearts to their 4, in green when you are well ahead through orange to red when you are well behind.
Other players' health on their name tag: a number with a heart like Hypixel's, a row of hearts, a number or a percentage, coloured by how hurt they are. Where the server already shows health under names you can replace it or keep the server's. Turning this on draws player name tags with Sour Client's renderer.
Tints a target you hit, model and hitbox, once the server confirms the hit did damage. Teammates, NPCs and anything that took no damage never flash. Wins over the Hitboxes colours while it lasts.
Draws outlines around nearby targets. The flash on a hit comes from Hit Colour.
Shows your inventory on screen without opening it.
Shows movement and click keys.
Minemen Club: when a match counts down, your opponent's stats for the mode you are playing are written in your chat - no menu opens. Hover the line for the rest. Anyone whose stats are exactly yours is marked NICKED. Also holds the Respawn Timer and Spawn Protection Timer HUDs.
On-screen hint when falling with cobweb available in inventory.
Shows your mouse movement as a dot that gets pushed around a box and springs back, with a trail - like Keystrokes for your aim.
Shows active potion effects and durations.
Shows the last registered hit distance.
Shows your hidden saturation - the food buffer that runs out before your hunger bar starts to drop.
Keeps sprint and/or sneak engaged until you cancel it, with an on-screen status display.
