Hector Vidal contributed to the Flow.Launcher/Flow.Launcher repository by focusing on improving the reliability and user experience of the preview feature. He addressed a UI issue where Result.Preview.Description was not displaying, ensuring that descriptions now render correctly in the interface. To further enhance robustness, Hector implemented a ViewModel property that falls back to the subtitle when the description is unavailable, reducing edge-case gaps and minimizing support queries. His work, primarily using C# and XAML for front end development, demonstrated attention to detail in stabilizing user-facing components, though the scope was limited to a single targeted bug fix during the month.
