Concerning the map, evopedia and maep should share their tiles and tiles once downloaded will stay there, so just viewing the map of some region should download the tiles. Perhaps maep also provides some other mechanism for bulk-downloading tiles for some region.

It is possible that there is a link to a specific spot on the map in an article but this article does not appear as an icon on the map. This is because a bug in the coordinate parser was fixed after the dump was made. Future dumps should not show this behaviour. So it is a bug in the dump that is already fixed in the software ;-) Nevertheless thanks for pointing it out.

I think RDJEHV's proposed behaviour for the home button is better than the current one, so this will be part of the next release. Thank you again.
