TileFinder

A rewrite, for Minecraft 26.3, 26.2 and 1.21.1, on NeoForge and Fabric.

• New finder screen, built with Vellum: search by name, by mod (@mekanism) or by a chest's custom name (in singleplayer; vanilla servers don't send those names); filter to blocks that hold items, fluids or energy, or to your starred spots; sort by distance, name, mod or count; change the radius with a slider.
• Finds what you'd call one thing as one thing: a double chest is one chest, a bed is one bed (1.21.1; 26.x beds have no block entity), a run of cable or pipe is one network (expand it to see each block), and wall signs, wall heads and banners list with their items.
• Decoration (signs, banners, heads, beds, pots) is kept out of the way under its own filter. Packs can hide or reclassify block entities with the tilefinder:hidden and tilefinder:decorative block entity type tags.
• Track one block or every block of a kind: boxes around each, a beam to the nearest, and a HUD line with the distance and direction. Targets drop off as you reach them. Everything shows through walls.
• Hover an item in JEI, REI, EMI (1.21.1) or any inventory and press the TileFinder key to find that block nearby. The finder's R and U buttons open recipes and uses in your recipe viewer.
• Stars are saved per world. Coordinates copy to the clipboard with one click.
• Settings in the finder's Settings tab, also from NeoForge's mod list and Mod Menu.
• Servers: /tilefinder [radius] [filter] works for players without the mod, in a chest menu, and points the way with particles. No library needed (GooeyLibs is gone).
• Scanning reads each loaded chunk's block entities instead of probing every block, so large radii are cheap.
