The street names on OSM maps, though generally quite sharp while using Mercator projection, is too small to read at a glance while bouncing over the landscape by someone with presbyopia, e.g., me. I typically zoom and pan the map using fingers on a laptop touchpad, and then snap to a zoom level using the routing info box (which has big buttons). But I often find it better to forego the snap, as this leaves larger print on the map. It occurs to me that a cheaply available zoom feature would be have a configurable snap level, perhaps continuously between 1 and 2, or perhaps to certain effective values. Reproducible: Always
