Add default indicator to rules table - #27724

eslint and biome both use a checkmark. Another, forward looking, alternative is to use (default) which would become correctness/complexity in the future.

Those options sound okay to me if you prefer them. We do use ❌ for removed rules, not sure if that would be confusing next to an eslint-style ✅ . I think some kind of icon is a little more appealing to me than (default) so that you can tell at a glance whether a rule is on- or off-by-default without having to process a bunch of category names. But it's a good point to consider how we'll present that information too. I think that will maybe be captured a bit better by regrouping the rules into Correctness, Suspicious, etc headings like the current linter headings. At least that's what I've pictured so far.

Yeah, grouping is an option too. But it may then cause issues for people that still need to look up the old groups :)

I don't really like the blue dot. It's not intuitive what it means, has low contrast in dark mode (also applies to the pencil but that's another issue), and is not really a design color that we use.

I can see how x and check can be confusing. But, I guess, they should never be next to each other because a removed (maybe use trash?) rule should never be a default rule?

Yes at worst they'd be "next to each other" vertically, not horizontally. I can just switch to a check mark.

I like this better too!

That's super helpful! I always wanted to suggest this too, but never got to reporting.

One more thing I also kept noticing about the documentation - there are some stable rules that have part of its behavior in preview and there's no indication of that in the table, so for users they may come as a surprise, when switching to preview.
In preview.rs there are currently 65 functions, so roughly there are ~65 rules that fall into this category. Not sure how many, but IIRC some of them were also missing preview description on their page. So maybe there's a way to standardize this.
