Latest Fabric version removed ModMenu integration. It appears that something else should replace it, but I have not found how to call the configuration menu with the new system. THere's no keybinding, or button, not sure how.??!

Update the CurseForge description then. It still says that you can edit it in-game with ModMenu.

Ah, I missed a sentence when I added the new section. It's gone now, thanks!

The config system has been changed out with a unified one as of 1.16.3 version 3 for both Fabric and Forge versions. The config file can no longer be edited from with-in the game and a text editor such as NotePad must be used. The config file is located at MINECRAFT_FOLDER/config/torohealth.json. Changes to this file should be reflected in real time if the game is running while the file is edited. The default file is shown below:

{
"watchForChanges": true,
"hud": {
"distance": 60,
"x": 4.0,
"y": 4.0,

"foeColorSecondary": -2147483393
},
