Sorry for making three posts almost in a row, but I noticed some other things. When scrolling outside the "edge" of the world it goes out then bumps you back in. It would have been nicer if it would have prevented you from going outside at all, as it takes a few noticable milliseconds to redraw the screen.
Also the menu buttons for scrolling the map doesn't work (altought the hardware keys work fine, and I don't see why anyone would want to use the menues for that as its much slower, so why have them in the menues?)
I was downloading maps for a large area (176mb in total) and while waiting I thought I'd check out the POI browser, but that seemed to freeze the download of the map, it was just sitting there not downloading anything, and the database file not getting any bigger if I du -h ed it in a terminal.
You should be able to select a few icons for POIs rather than just having a dot, would be much more usable.
Also could you make the description part of a POI longer than two lines? 5-8 lines or so would be optimal, I use maemo mapper for geocaching and store down alot of info about each location, and having to scroll after reading two lines is extremly annoying.
The screen rotation feature is useful, but when you're standing still and the GPS position is drifting its a bit annoying that it keeps rotating in random directions, especially in areas where the position isn't very accurate it could jump a few meters here and there every few seconds and it will rotate in different ways. If there could be some lower speed that it has to go above to count to rotate the screen that would be nice. Maybe you didn't notice because there is good accuracy in your area, but I'm so far north that EGNOS (europeean version of WAAS) doesn't work here, so it can be bad at times. Would be nice if the same lower speed limit applies to adding points to the route so it doesn't look like you're going around in circles when you're actually standing still. Having this limit just below walking speed would be optimal, maybe it could be a configurable value.
