That way a reroute after it being detected you are a reasonable way off course would be the default, however the user would have a simple way (double tap screen within 10 seconds of the message) to disable the reroute. the message could even be "rerouting in 10 double click to disable".

OK, thats seems doable.

Is this behavior normal during the tile download?

Downloading tiles for a large area and/or full zoom range means downloading many thousand separate tiles, which can be quite resource intensive. But it really shouldn't make the application totally unresponsive. I'll look what cane be done to fix this and also how to optimize the whole process, I also opened a ticked for this issue.

Are you running your N900 overclocked ? That could explain the increased temperature during the quite CPU intensive tile download. Could you perhaps try to do the same batch download with normal kernel for comparison ?

there was already a feature request for this a while ago, I am currently investigating how to do this in the most efficient manner.

good idea, I have added this to the rotation feature request.

Well, thats quite a big download.

There is not an easy answer. Size of the map images varies widely, some are 0,1 KB others 18-20 KB, this means taht it is not known how much will be actually downloaded and it can't be reliably estimated.

But! -> ModRana actually has a feature for checking the total download size of the current batch. Just tap the infobox instead of the start button and modRana will start checking the total size by skipping aready available tiles and looking on the metadata without actually downloading the whole tiles.

Because the documentation on http://www.modrana.org is outdated and I have to finally start updating it.

BTW, modRana now has its own domain, www.modrana.org
