Suggested Changes
Right now, all non-deprecated rules are placed in the same list in the sidebar. That includes formatting rules mixed with other, more useful rules.
Proposal: similar to how deprecated rules have their own section at the bottom, let's put all formatting rules (ones that should be replaced with a formatter such as Prettier) down in their own section? That way they don't clutter the space and take focus away from the more useful rules.
