📝 Walkthrough

Walkthrough

The page adds a device-location button and fallback handling. It updates geolocation permission checks. It labels beta-private modules and links them to Google Play testing URLs. It also adjusts logo and brand-title shadows.

Changes

Map and module updates

Layer / File(s)	Summary
Location control UI index.html	The page adds the location button and circular control styling. init() stores the map in currentMap and wires the button handler. Logo and brand-title shadows are updated.
Device location flow index.html	The button requests device coordinates and centres the map. The flow uses IP and default-centre fallbacks. centerMapOnDeviceLocationNavigator now checks geolocation availability and permission state.
Beta module link handling index.html	Beta-private module titles include [BETA]. Their links use the Google Play testing URL. Other modules retain the regular Play Store URL.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 1fd90

When device geolocation fails or returns invalid coordinates, the map may remain centered on a stale or unrelated location instead of using the available fallback location. The change is otherwise localized, but this bounded behavior issue should be addressed or explicitly accepted before merging.

Pull request overview

This PR enhances the single-page map UI by adding an explicit “Use my location” control and refining how geolocation and store links are handled within the map marker info windows.

Changes:

• Added a “Use my location” floating button and wiring to request geolocation on demand.
• Updated geolocation logic to incorporate a Permissions API check during initial centering.
• Enhanced marker info windows to label beta-private modules and link them to the Play testing URL.

Suppressed comments (1)

index.html:186

• If the geolocation request fails (permission denied, timeout, etc.), the click handler only logs a warning and does not apply any fallback (IP/default). This makes the "Use my location" button a no-op in common failure scenarios.

				function (error) {
					console.warn('Navigator geolocation request failed:', error);
				},

index.html:250

• In centerMapOnDeviceLocationNavigator, the return permissionCheck... line is missing the surrounding indentation, which makes this block inconsistent with the rest of the file and looks like an accidental formatting error (easy to miss in reviews/merges).

			var permissionCheck = navigator.permissions && navigator.permissions.query
				? navigator.permissions.query({ name: 'geolocation' })
				: Promise.resolve({ state: 'prompt' });

return permissionCheck.then(function (permissionStatus) {
				if (permissionStatus && permissionStatus.state === 'denied') {
					throw new Error('Geolocation permission is denied');
