If you make an app to teach where countries are on the world map, you ran into an annoying problem: A lot of countries are rather small (looking at you, Antillean Arc). If you make an exercise like "Find Anguilla on the map" the learner has to either zoom and search (as in my first implementation of such a game) or you just require to find the country roughly, without zooming. I did this in my second implementation of such a game. This seems like a good solution, but it's actually rather confusing; users intuitively want to zoom. The UI sketched out here could solve this struggle.
