📝 Walkthrough

Walkthrough

Updates adjust click handling in PersonalSectionItem to only toggle when children exist and remove the fallback open action. LeftSidebarView gains an effect to synchronize local config state with changes to initialConfig by invoking setConfig(initialConfig).

Changes

Cohort / File(s)	Summary
Sidebar interactions and config sync apps/roam/src/components/LeftSidebarView.tsx	PersonalSectionItem: title onClick now calls handleChevronClick only when children exist; otherwise no action. LeftSidebarView: added useEffect to update config state whenever initialConfig changes via setConfig(initialConfig).

576-578: LGTM! State synchronization pattern is sound.

The effect correctly syncs local state with external config changes, supporting the use case described in the past comment (updating state when sections are added or moved). The pattern of maintaining local state for optimistic drag-drop updates while respecting external changes is appropriate.

Based on the past review comment from sid597.
