Compact F3

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): 1140 ticks with errors, first: a HUD element threw java.lang.NoSuchFieldError: Class net.minecraft.client.Minecraft does not have member field 'net.minecraft.client.Options options'.

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3)

In the author's words

A mod that reduces the useless information from F3, can be toggalable with F8.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file compactf3-1.3.3.jar. The scan reads the mod's classes; it does not run them.
