The columns property is defined but never used in the implementation. The menu uses a VStack layout instead of a grid layout, making this property unnecessary.

The dispatch function is called without importing or defining it in this file. This suggests a missing import or the function should be accessed through the store's dispatch method.

The columns property was leftover from the initial grid layout design and is no longer needed after switching to vertical list layout. Addresses Copilot review comment.

The .hide() modifier is applied to a grid icon that appears to be dead code since it's always hidden. Consider removing this unused UI element entirely to reduce code complexity.

The logic state.selectedTab.supportsLoadMore() is duplicated in multiple places (lines 26, 31, 36, 49). Consider extracting this into a computed property or helper method to reduce code duplication.

The rotation angle continuously increases by 180 degrees on each toggle, which will cause the chevron to rotate multiple full circles over time. Use a conditional assignment: rotationAngle = newValue ? 180 : 0.

The login check logic tab.needsLogin() && !AccountState.hasSignIn() is duplicated on line 47. Consider extracting this into a computed property or local variable to avoid repetition.

The animation modifier is applied to the entire ZStack but only responds to isShowing changes. Consider moving this animation to the specific views that need it, or ensure isShowing properly controls the entire view's visibility.

[nitpick] The variable supportsLoadMore is used only once and adds unnecessary complexity. Consider directly assigning state.hasMoreData = state.selectedTab.supportsLoadMore().

- Added scrollToTop state property to FeedState - Modified FeedReducer to trigger scroll after filter change data loads - Updated FeedPage to use both state and global scroll triggers - Ensures users see new content from the beginning after filter change This improves UX by automatically scrolling the feed list to the top when users select a different filter category, preventing confusion from seeing mid-scroll content from the previous filter. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
