Excellent app and thank you for making it possible, can I just ask about some things I noticed.

1. Can I use it completely offline for navigating or simply browsing the map for street names and house numbers?

What I did: Downloaded the daemon from the store, installed the map for my country, set up "offline" in preferences, but I still see a pixelated image/map of my city/country and it gets worse with zooming. Once I go online, it starts downloading everything on all zoom levels, i.e. I scrolled through my city on all zoom levels to get the map more or less visible/scrollable while in offline mode, is there another way to do that which I missed?

2. Would it be possible to have a search by house numbers?
3. Would it be possible to have say garmin or navitel maps converted to be used with Marble? I have bought them while I was rocking my 5800 and they're very detailed (not that openstreetmap isn't, but paid maps are constantly updated etc.)
Thank you!
