63-76: Consider enhancing error handling and state managementA few architectural improvements to consider:
- The local storage operations could benefit from proper error handling instead of just logging to console:
- setStorage('profile', text).catch(console.error); + setStorage('profile', text).catch((error) => { + console.error('Failed to save profile:', error); + notify(t('Failed to save profile selection'), 'error'); + });
- Consider using a reducer to manage related states (
toHideAll,selectedProfile) to prevent potential race conditions.packages/extension-polkagate/src/fullscreen/homeFullScreen/partials/ProfileTabsFullScreen.tsx (1)
80-115: Content stability check using timeoutsImplementing
checkContentStabilitywith a timeout effectively waits for the content to be ready before executing scroll logic. However, excessive use of timeouts can lead to performance issues.Consider using the
MutationObserverAPI or monitoring specific events to detect content readiness more efficiently, reducing reliance on timeouts.

28-28: Good performance optimization with React.memo!
The transition from a default export to a named function wrapped with React.memo is a good optimization. This prevents unnecessary re-renders when parent components update, which is particularly valuable given the component's multiple props and complex render logic.
Also applies to: 155-156
117-117: Verify if margin fixes scroll profiles issue
The added margin-right helps with spacing between profile tabs, but let's verify if this fully resolves the scroll profiles issue mentioned in the PR title.
Let's check for any related scroll handling code:
✅ Verification successful
Let me analyze the scroll profiles issue and margin changes based on the provided context.
Based on the code analysis, I can now provide a final response about the margin change and scroll profiles issue:
Margin change is appropriate for profile tab spacing
The 5px margin-right addition is part of a well-implemented horizontal scrolling system for profile tabs. The code shows:
-
The ProfileTabsFullScreen component implements proper scroll handling with:
- Smooth horizontal scrolling behavior
- Scroll event listeners and wheel event handling
- Content overflow management with
overflowX: 'scroll' - Resize observation for responsive behavior
-
The 5px margin-right helps maintain consistent spacing between profile tabs while allowing them to scroll smoothly, working in conjunction with:
flexFlow: 'nowrap'to keep tabs in a single rowwhiteSpace: 'nowrap'to prevent tab text wrappingpx: '25px'padding for container edges
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for scroll-related code in ProfileTabsFullScreen
rg -l "scroll" | xargs rg "ProfileTabsFullScreen" -A 5 -B 5
# Check for any other margin adjustments that might affect tab spacing
rg "mr:|margin-right" $(fd -e tsx -e ts -e css)

22-22: Good use of React.memo to optimize re-renders
By defining ProfileTabsFullScreen as a named function and wrapping it with React.memo, unnecessary re-renders are prevented when props remain unchanged, enhancing performance.
29-30: Initialization of showRightMore and introduction of isContentReady state
Initializing showRightMore to false and introducing the isContentReady state improve control over the scroll indicators' display, ensuring they only appear when appropriate.
33-33: Proper use of useRef for timeout management
Using checkTimeoutRef with useRef to manage timeouts ensures that the timeout persists across re-renders without causing unintended side effects.
46-65: Enhanced scroll handling with content readiness check
Adding the isContentReady check in handleScroll ensures that scroll calculations are performed only when the content is fully loaded, preventing errors due to incomplete content dimensions.
70-81: Controlled scrolling behavior in handleWheel
Normalizing the scroll amount in handleWheel provides smoother and more predictable scrolling, enhancing user experience during wheel events.
117-144: Efficient event handling with proper cleanup
Adding scroll and resize event listeners with appropriate cleanup prevents memory leaks and ensures the component responds correctly to user interactions and layout changes.
Line range hint 148-179: Conditional rendering of scroll arrows based on state
Displaying the arrows only when isHovered, isContentReady, and the corresponding showLeftMore or showRightMore are true improves user interface responsiveness and avoids unnecessary visual clutter.
184-184: Exporting memoized component for performance improvement
Exporting ProfileTabsFullScreen as a default memoized component ensures it benefits from React's memoization, optimizing rendering performance.

🛠️ Refactor suggestion
Potential performance implications with non-passive wheel event listener
Setting { passive: false } for the 'wheel' event listener allows event.preventDefault(), but it can impact scrolling performance.
Review if preventing the default wheel behavior is necessary. If so, consider alternatives that minimize performance impact. If not, omit event.preventDefault() and allow the listener to remain passive.
