TNT Timer UI
by ItsMaas_
TNT Timer UI shows a live fuse countdown in the action bar for any primed TNT block within 40 blocks of the player, whatever lit it.
What it does
Once a TNT block is primed, whether by flint and steel, a redstone chain reaction or another source, the countdown appears above the hotbar and keeps ticking down until the block explodes. The display covers TNT that is primed near the player, so a player who lights a block can see how much time is left before it goes off.
The mod suits survival play, where lighting TNT can feel risky, and redstone builders who set up traps or player-versus-player arenas and want to know how long they have to run. It changes nothing about how TNT behaves and does not alter any other part of the game. It is server-side only, so players join without installing it, and the server needs Fabric API. The files cover 26.1.1 – 26.2 and the mod is not open source.

Use cases
Surviving chain reactions
A player who sees a redstone chain reaction start can check the countdown and decide whether to move away before the blast.
Redstone traps and PvP
Builders running player-versus-player setups can use the timer to judge how long a trap leaves a target before it fires.
Who it’s for: Survival players who find lighting TNT stressful, and redstone builders and server owners who run trap or arena games.
