 ## TODO
 
 ## Future
-Add airport markers and counters for arr/deps
-Show ATC polys and state from controllers API
-Add ATC markers for tower, gnd, dep
-Use AFV to get extended sectors
+
+* Theme switch light / dark
+** Turn off POI labels at high zoom
+
+* Markers clickable
+* Modal or inline window
+* Geocoder search for marker names
+
+* Show ATC polys and state from controllers API
+* Add airport markers and counters for arr/deps
+* Add ATC markers for tower, gnd, dep
+* Use AFV to get extended sectors
+* Switch icons between prop and jet based on callsign or type.
+  Filter aircraft_type by types from https://vatstats.net/
+* Use nav API for progressive taxi or draw on ground map routes
 
 ### Current stats
 In FIR now
+Top types
+Arr / dep counts
 
 ### Stored stats
 Traffic heatmap (DB needed)
