More Debug Info!
by alces
More Debug Info! adds extra inspections to the F3 debug screen, which shows game and system details.
What it does
The F3 debug screen already lists many values, most of which are hidden by default. This mod adds further inspections to that screen and offers options to customize what it displays. Pressing F3 and F6 together opens the customization options. It is a client-side mod, so only the player needs it, and it requires Fabric API. Files are published for Fabric and NeoForge, for game versions 1.21.11 – 26.1.2, under the GNU General Public License v3.0 or later, which makes it open source.
