We have a large room with odd-shaped furniture. Setting no-go zones is frustrating as there are no 'measurements' to the map. Ideally, there would be an option to turn on a grid showing feet/meters, in which more precise adjustments could be made when setting a zone. Right now it's frustrating creating a zone, watching my S6 MAXV make cleaning run, slightly adjusting the zone area, repeat and rinse, etc.
Other benefit would be to access the map in a laptop or display monitor. Using the small screen on a mobile app is not as much fun or precise as doing so with a web browser or dedicated compute app.
