November 2024 monthly summary for feenkcom/lepiter: Delivered a focused UI enhancement to error presentation during local sync operations. The error window now uses the string representation of LeLocalSyncErrorStatus as its title, providing a descriptive, context-aware presentation without altering underlying monitoring behavior. The change is isolated, low-risk, and ready for broader use in future error-handling improvements. This aligns UX with diagnostics and reduces troubleshooting time for users and developers.
