This software is excellent. Elegant interface and well drawn chart. The only drawback I've found is that it doesn't work so well with my touchscreen Sony Ericsson W960. This has a scrollwheel, but no left/right buttons, so it's impossible to move the chart in azimuth.
The workaround I've used is to use the goto feature to get to the right direction in the sky.
I'm guessing starryalley doesn't have a whole lot of time to devote to this project, but touch screen support would be the icing on the cake for me. An alternative would be to have some other method for navigation, though I don't think there are any keypad keys left :)
