Yes, there is a lot to improve. I also have my gripes about what POI are kept from the detail view to the zoomed out view, or how I'll completely lose a location if I happen to misclick on some random POI that happens to fall under my finger on the edge of the screen.
On the rougher part of the maps, I often get back to satellite view and/or StreeView if available (even as they sometimes don't show the same info as they come from different points in time -_-;). It's a handy backup that I don't get on the open source map apps

And for unfathomable reasons Google Earth (the desktop version) can show historic aerial imagery, but no historic street view pictures, whereas Google Maps works just the other way round – you can view historic street view photographs there, but no historic aerial/satellite imagery. (And the browser version of Google Earth apparently can't do either.)
