Oh, I just noticed a minor issue. Using a light theme, the text 'Pure Maps' on the cover is almost invisible. This is partially because light themes aren't optimised yet (lots of light colours on light backgrounds), but looking at Jolla's own applications, they usually use white/black text on their covers instead of the theme-dependent colours, so I think it would make sense to do it the same way for Pure Maps. OSM Scout Server already uses white/black text on the cover, too.
