One of the things I didn't spend too much time with at the beginning of the development of WiFi Explorer was filtering. As the tool matured, it was more than evident that some filtering capabilities were needed. Nevertheless, I didn't want to make anything overly complex. Filtering had to be quick and easy to use, and more importantly, the syntax used to create filters needed to be "natural." With these goals in mind, I've been working over the years on different ways to filter scan results in WiFi Explorer and WiFi Explorer Pro.
