v1.5.8 — In-App File Viewer

Excel dashboards are now viewable directly inside the app — no Excel required. A new Files tab renders your .xlsx output via a built-in viewer with sheet selection and smart column sizing. The Sleep Dashboard Excel output also gets a visual upgrade: phase bar cells now carry letter labels (D/L/R/A) in contrast color, readable both in Excel and in the viewer.

What's new:

• Files tab — third tab in the app, shows all .xlsx files from dashboards/. Sheet selector appears automatically for multi-sheet files. Chart sheets are filtered out — only data sheets shown. File list refreshes on tab switch and after every dashboard build
• Open File button — opens the selected file in your system default (Excel, LibreOffice, WPS)
• Sleep phase labels — each phase-bar cell in the Sleep Dashboard Excel now shows D / L / R / A in matching contrast color

Downloads:

• Garmin_Local_Archive_Standalone.zip — recommended, no Python required
• Garmin_Local_Archive.zip — standard, Python 3.10+ required
