First of all, I'd like to specify that I don't code or anything, so sorry if I mention things that aren’t even possible to do or confuse things that have nothing to do with each other.

1. More control over fog types
In version 0.6.5 of Sodium Extra, I could disable the environment fog added in 1.21.6 by enabling Multi-Dimension Fog and matching the fog distance to my render distance for the Overworld which completely removed that new environment fog while keeping the border and cloud fogs.

Now in 0.6.6, it looks like I can only disable whole categories (e.g., all “Atmospheric Fog”), which removes everything: border fog, cloud fog, environment fog even though I only want to remove one. It’d be really helpful to have a way to toggle fog types within each category.

2. Percentage-based fog distance feels less Intuitive
I noticed that fog distances are now controlled entirely by start and end multipliers instead of fixed chunk values. This means the fog start and end distances are expressed as a percentage of the current render distance rather than an absolute chunk count.

Even though it probably offer more flexibility technically, it feels less intuitive to me as a casual player. For example, I used to simply set my Nether fog to match my render distance (24 chunks) and know exactly where the fog would start. Now, with multiplier sliders that can go beyond 100% (up to 300%), it’s harder to know what percentage corresponds to a specific chunk value without doing math or guessing.

That said, I get it that for fluid fogs, using chunk counts wouldn’t make sense, so maybe a hybrid system could work: chunk-based controls for dimension fogs, and multiplier or block-based controls for fluid fogs? Or maybe make it a setting apart?

3. Nether, End, Boss fogs merged?
I also noticed that the Nether fog settings seem to be merged together with the End and boss fogs in the same control group. Does this mean I can no longer adjust the Nether fog distance independently from the End dimension’s fog or the fog effects during the boss fight? For example, if I want a different fog distance in the Nether than what appears in the End or during the Dragon fight, it seems impossible now.

The vanilla fog distance in the nether is also capped once you go over a certain render distance, so a distance of 300% inadvertently limits how far you can see in the nether, regardless of your actual render distance. At larger values (say, 40 chunks), this is very noticeable when traveling between dimensions.
