-### 11. Navigation & Routing (Implemented, Awaiting Integration)
+### 11. Tile Provider System & URL Templates
+
+**Design approach:**
+- **Flexible URL templates**: Support multiple coordinate systems and load-balancing patterns
+- **Built-in providers**: Curated set of high-quality, reliable tile sources
+- **Custom providers**: Users can add any tile service with full validation
+- **API key management**: Secure storage with per-provider API keys
+
+**Supported URL placeholders:**
+```
+{x}, {y}, {z}          - Standard TMS tile coordinates
+{quadkey}              - Bing Maps quadkey format (alternative to x/y/z)
+{0_3}                  - Subdomain 0-3 for load balancing
+{1_4}                  - Subdomain 1-4 for providers using 1-based indexing
+{api_key}              - API key insertion point (optional)
+```
+
+**Built-in providers:**
+- **OpenStreetMap**: Standard street map tiles, no API key required
+- **Bing Maps**: High-quality satellite imagery using quadkey system, no API key required  
+- **Mapbox**: Satellite and street tiles, requires API key
+- **OpenTopoMap**: Topographic maps, no API key required
+
+**Validation logic:**
+URL templates must contain either `{quadkey}` OR all of `{x}`, `{y}`, and `{z}`. This allows for both standard tile services and specialized formats like Bing Maps.
+
+**Why this approach:**
+Provides maximum flexibility while maintaining simplicity. Users can add any tile service without code changes, while built-in providers offer immediate functionality. The quadkey system enables access to high-quality satellite imagery without API key requirements.

 ## Roadmap
 
 ### Needed Bugfixes
+- Update node cache to reflect cleared queue entries
 - Are offline areas preferred for fast loading even when online? Check working.
 - Fix network indicator - only done when fetch queue is empty!
 
 ### Current Development
+- Decide what to do for extracting nodes attached to a way/relation:
+  - Auto extract (how?)
+  - Leave it alone (wrong answer unless user chooses intentionally)
+  - Manual cleanup (cognitive load for users)
+  - Delete the old one (also wrong answer unless user chooses intentionally)
+  - Give multiple of these options??
+- Nav start+end too close together error (warning + disable submit button?)
+- Persistent cache for MY submissions: assume submissions worked, cache,clean up when we see that node appear in overpass/OSM results or when older than 24h
+- Dropdown on "refine tags" page to select acceptable options for camera:mount= (is this a boolean property of a profile?)
+- Tutorial / info guide before submitting first node, info and links before creating first profile
+- Option to pull in profiles from NSI (man_made=surveillance only?)
+
+### On Pause
 - Suspected locations expansion to more regions
 - Import/Export map providers
 - Swap in alprwatch.org/directions avoidance routing API
 - Clean cache when nodes have disappeared / been deleted by others / queue item was deleted
 - Improve offline area node refresh live display
-- Add Rekor profile
 
 ### Future Features & Wishlist
 - Update offline area nodes while browsing?
 - Offline navigation (pending vector map tiles)
+- Android Auto / CarPlay
 
 ### Maybes
 - Yellow ring for devices missing specific tag details
