I know that it can't fit all the cameras on the map. But my problem was that it was stacking up all cameras nearby into one so that it's not showing all the cameras in it's place and when selecting camera from "Nearest webcams" section it goes to the camera but shows it in wrong location.
So basically, Windy is taking all nearby cameras that's close to point A and then puts all the cameras into the point A where you can select the camera from "Nearest webcams" section. When selecting camera from the section, there's a change that Windy doesn't show the actual location of the camera. So wrong location. Basically, if camera A is in point A and if choose camera B, Windy might show that the camera B's location is in point A even though camera B's location is in point B. Very annoying bug and feature. I do not like it.
Also english is not my native language.
