I put my whole settings panel in one atom, and editing the theme somehow re-renders the notifications toggle too.
What you'll have at the end
A settings panel where changing one field's atom leaves every other field's render count at zero
You need
A Jotai-powered settings or preferences panel where more than one component reads a single atom holding several fields together as one object.
Not covered
Deciding whether this state needed a shared atom in the first place. That decision comes before this one, which assumes more than one component already shares the atom.
Leans on
A Zustand selector triggers extra renders
the same unrelated-field re-render symptom on a Zustand store instead of a Jotai atom; the fix there is a shallow-comparing selector, not splitting the store itself
Split a growing Zustand store into slices
splitting a store for file size and ownership clarity rather than for render isolation, and for Zustand's single-store shape rather than Jotai's atoms
