3) What are the downsides of using the "external" SD card to store the tiles? Not an issue in My Docs at the moment, but if I have a lot of offline tiles stored, I may want to shift them to save space in the future.

Again, many thanks for the application.
You can run Modrana on the linux computer as well, and download the maps there and then transfer them to the N900.

The problem with saving to extrernal SD is with storing them as individual tiles, which is not efficient for small files on the filesystem (FAT) and takes up a lot of extra space ( quickly adding up to 20 GB if you have lots of tiles stored)..

True, these maps are more of a fun addition, adds some bragging rights (look at what MY phone can do like the historic, moon and mars maps in Marble)

Yes, I forgot Maemo.org automatically resizes them, IŽll upload a full resolution one.

Cloudmade Tourist + Google public transport overlay (50%)


Stamen watercolor + Google weather overlay (100%)


MapQuest EU + Opensignal (50%)

And a setting in Options to turn this behavior on/off.

Also, any ideas how I should set it for the different layers (eq. how often are they updated ?)?
A option for setting these in map layers (per mode state list setting, this button doesnt do anything yet?)) would be nice, maybe only for weather and traffic ?, Once every few hours for things like weather. For traffic more often. I thinmk at least once every time modrana runs (with network connection).

This works fine, I already noticed the weather icons not being updated and deleted the maps.
