* Improve tile cache:
** If cached tiles have changed, possibly also try (async) updates of other cached zoom levels covering this area
** Pre-cache tiles in adjacent areas and possibly zoom levels
+*** Feature to download all maps up to a certain resolution for some area around the current point
* Improve texture cleaning algorithm
-* Show a notification when we are loading tiles or saved data
-* Display length and duration of track
-* Display movement speed
-* Display location accuracy
-* Show a better visible marker for the current location, possibly also indicating movement direction/speed
-* Smooth animations for zooming, probably using some WebGL magic
-* Use available larger/smaller tiles with resizing as loading placeholders while zooming in/out
+* See if we can secure OSM login (investigate OAuth)
+* UI improvements (non-map):
+** Show a notification when we are loading tiles or saved data
+** Display movement speed
+** Display location accuracy
+** Find better UI for track length/duration display
+* Map/track display improvements:
+** Speed up track drawing:
+*** Only draw lines that are visible
+*** Reduce lines to draw by eliminating unneeded detail (based on zoom level)
+*** Make track drawing async and hooked up to requestAnimationFrame()
+** Show a better visible marker for the current location, possibly also indicating movement direction/speed
+** Smooth animations for zooming, probably using some WebGL magic
+** Use available larger/smaller tiles with resizing as loading placeholders while zooming in/out
* Better GPX saving implementation [blocked by missing web APIs]
** Set file name to save into to a good default (date + maybe some location name)
* Possibility to auto-rotate map to match movement direction
* GPS details display (satellite visibility/strength) [blocked by missing web APIs]
* Magnetic compass display (using orientiation API)
+* Integrate reverse geocoding, using http://wiki.openstreetmap.org/wiki/Nominatim
+ e.g. http://nominatim.openstreetmap.org/reverse?format=jdon&lat=48.2051107&lon=16.3449773&zoom=14&addressdetails=1
