I've done my first experiments and I'm very impressed! I'm using modRana 0.41.1(GTK version).

A couple of questions:
EDIT: Disregard requests to configure location to save tile data, as I see it has been already asked.

- Is there a way to set the location where tiles are downloaded? I can't find that option anywhere. For that matter, is there also a way to configure where modRana looks for the navigation data?
Please, allow for the configuration of the location to save tiles and navigation data. I would rather put it in the micro SD card because it's easy to replace. I can even put it on a second N900, and use the data as well. Until then, maybe some symlinking is in order.

- When I am setting up the batch download of tiles, I clicked to calculate the size. When it calculates the size, it looks like it keeps calculating the full size (I suppose it downloads and deletes every single tile?) It would be better probably to just estimate by downloading a representative number of random tiles and then extrapolating (sorry if that's the way it already works, I might have not waited enough).

- Another comment regarding the last point: When it is calculating the size, if you click back to exit the menu, the application becomes nonresponsive and needs to be closed. I guess the threads that are downloading / calculating the size of the tiles are still running.

Great program! I think I'm going to use it for the first time tomorrow.

Talking of which, does Google really disable batch downloading of tiles? Because that sucks. Anybody knows how to get around that?

Martin, I just had a cool idea: Since Google disables batch download, but downloading tiles in normal use is allowed, wouldn't there be a way to simulate a route that would cover all the target tiles? Unfortunately I suppose you would have to run the route as many times as the zoom levels you have selected, and change zoom level at each pass. And, the route would probably be huge and hard to compute. A strange benefit is that this would take less space, because it wouldn't download tiles that you wouldn't see during normal use (tiles for places unaccessible within the view distance for the range of zooms selected). Also, you might have to be observant of the speed at which the route is run.
