About this Mod

Better Vanilla F3

Opinionated mod to bring back the usual familiar f3 order of things.

1.21.9 adds new debug overlay stuff, but the sections end up in
seemingly random places.

This mod hard-codes the order of those sections (and the side they are
on), to match earlier versions.

Features:

puts debug overlay rendering behind GUI to match earlier behavior
fixes E counter on versions before 26.1
pie chart scaling and disabling of its background
fix the bug where f3 is visible when hud is hidden
put the section relative pos in its old place
(>=26.1) add day counter back to local difficulty
