Fair enough, and I agree that the ability to add any random map location as a POI would be very useful (i'm sure MartinK will consider this when he sees your post, probably just an oversight that he missed your original request).

However, POI's or Street names will work as I described in 99% of cases, so I don't see it as a biggie to wait until the developer gets around to looking at it for you. The other stuff he's working on is important to optimise download sizes, and if you're ever caught in your siberian wastes then you'll be needing a large preloaded set of map data regardlss of POI's (as you'll have bugger all mobile coverage I reckon).
