First off, great app! I'm getting more and more used to it especially when walking around the city. One of these days I'll figure out how POIs work ;-) Maybe there could be a POI mode where clicking on the map opens a dialog to add a POI, just name and category.

Another suggestions. Would it make sense to have zoom levels definable where only selected levels would be used in both zoom and automatic download? This could help keep down the amount of storage used.

Again, thanks for great work!
