Features of the Full Version
Full version offers both additional technical features and user interface
improvements for frequent, on-the-run, use:
- Store maps on VFS (memory card) - save internal memory.
- Efficient VFS support - large, real-world, quick maps.
- Last map used is automatically remembered and opened on startup.
- For each map used, last position used is remembered - you can switch
to other map and back and your position will not be lost.
- Last selected object is highlighted (with on-screen target mark).
- Search usability improvements: last selected object is remembered,
you can start search by directly writing the first letter of the name you need.
More features are planned!
