DuraHUD

Each display can be styled and positioned on its own. Armor durability reads from the helmet, chestplate, leggings and boots, while the main hand and off hand report their items separately. Durability can be shown as a percentage or as remaining points, with green, yellow and red bands that the player sets with thresholds and hex colors, so the state of each piece is visible at a glance without opening a menu.

The potion display lists active effects with their level in roman numerals, a remaining time in minutes and seconds or plain seconds, and a duration bar that takes the effect's own color. Effects can be sorted by ending soonest, longest left, name, or with helpful effects first. Infinite effects are shown as well. The vanilla effect icons can be hidden and replaced by the HUD entries, and the HUD can be moved away from the menu buttons that tend to open over it.

The mod runs on Fabric and is open source under the MIT License. It is client-side only, so a server needs nothing installed, and players can use it in single-player as well as on a server. Files are published for 1.21.1, 1.21.4 and 1.21.11, with 1.3.0+1.21.11 for 1.21.11 as the latest file. Fabric API is required, and Mod Menu is optional for opening the settings screen.
