Because some mod new effects do not always display the icon correctly, for the sake of unity or for the sake of concise display, I think it is also a good choice not to display the icon

There already is a setting to disable the effect tooltips
I'm not sure if I want to start doing such granular configs

Are there any known problematic effect icons?

I see, it was written in tooltips so dont show the icon,these will show tooltips twice, and some food just no effect tooltips

I don't understand what you are trying to tell me there

If the config is enabled existing effect tooltips should be removed (and replaced with the custom ones from this mod)
If it is disabled no effect tooltips will be added / no existing ones will be removed

As mentioned above, there is a config to disable the custom tooltip logic for effects
