I'm testing v 0.4.2. Here are my initial comments:
- a help option might be good to get people going. Mention things like shortcut keys and any other common questions.
- when I press the Back key when I'm in Options, it should really prompt before discarding any changes.
- not sure of the value of this, but could you display the current direction to the nearest 0.5 degrees instead of the nearest degree?
- when quitting from the program, it asks "Cancel/Quit?". The default is Cancel, but normally I'd want to Quit. Could you change the default? Most other Blackberry programs would offer the options Yes or No, and I would be able to press Y or N. It would be nice to be standard.
- while tracking, the display shows, E, N, speed, direction, height, time since start, total distance so far and tracking point number. While playing back, it's the same, but the distance is always the total. Could you display the distance to that point *and* the total?
- The change notes say "add shortcuts to jump to first ('7','s') and last ('9','e') track point". On an 8800, 2 is on the E key, and 4 is on the S key.
- I'd like the option to display a previous track while recording a new one. This is so that I can either follow a previous path, or find my way back to the start. I guess you'd need another colour on there to distinguish the two tracks.
- It might be useful to be able to load a track, then continue tracking on it. This would be useful on multi-day trips, where you might need to close the application overnight, but continue the next day.

Other than that, it looks very good. (It's not spyware is it?)
