// 0. Minimize memory used for index & improve time for read index
//// TODO for releasing version
// 1. POI SEARCH NEAR TO YOU
// 2. FIX BACK TO your location & gps & point of view (may be compass)
// 3. Revise UI icons/layout
// 5. Enable city/streets/buildings index
// 7. Search for city/streets/buildings!
// 8. Enable change POI directly on map
// 9. Log to see when exception occurred (android)
// 10. Specify auto-rotating map (compass).
// 11. Print out additional info speed, altitude, number of satellites
// 12. Show point where are you going (the arrow not the point)
// 13. Save point as favorite
// 14. Show zoom level directly on map
// 15. Investigate interruption of progress (is it available & how to support it)
// -------------------
// TODO ANDROID
// 0. Minimize memory used for index & improve time for reading index
// 1. POI search near to map location (show categories & type). First cut. (implement incremental search)
// 3. Revise osmand UI. Preparing new icons.
// 2. Showing compass on the map : use device compass if exists(?)
// 5. Search for city/streets/buildings
// 9. Config file log & see log from file (when exception happened to see from device)
// 11. Print out additional info speed, altitude, number of satellites
// 8. Enable change POI directly on map (requires OSM login)
// 13. Save point as favourite & introduce favourite points dialog
// 14. Show zoom level on map
// 15. Investigate interruption of any long running operation & implement where it is needed
// 16. Support open street bugs api.
// 17. Enable go to location specifying coordinates
// 18. Implement go to point
// 19. Show how map is rotated where north/south on map (do not consider compass)
// 20. Implement save track/route to gpx (?)
// BUGS Androd :
// FIXME Bugs Androd :
// 0. FIX TODO for partial loading rotated map
// 1. When firstly run osmand navigation (from notification bar) show map & go to menu shows desktop.
// No chance to close application
// 3. Fix progress information (loading indices) for android version
// 4. Fix when POI selected & enable button backToLocation
// TODO SWING:
// 1. download tiles without using dir tiles
// 2. Config file log & see log from file
// 3. Reinvent index mechanism (save in zip file with tile indexes, save city/town addresses separately, read partially !)
// 4. Invent different file extensions for poi.index, address.index,...
/// SWING version :
// TODO :
// 1. Accept amenity as way
// 1. Fix TODO in files
// Max letter :
// 1. Fix bug 1
// 2. Create for each screen activity
// 3. Implement incremental search (reduce first time display to 10 & depth 2)
// 4. Improve navigate back/forward between screens
// 5. Implement exit confirmation
// DONE ANDROID :
// 12. Show information of where are you going (the arrow on the map)
// 10. Specify auto-rotating map (bearing of your direction)
// DONE SWING
// 3. download tiles without using dir tiles
// 4. Config file log & see log from file
// 5. Reinvent index mechanism (save in zip file with tile indexes, save city/town addresses separately, read partially !)
