I''ve a couple of suggestions for the developers.
1) In the Diagram Window type graphs, provide an option to display speeds in a logarithmic-type scale. This would provide more space for lower speeds and relatively less for greater speeds. This is similar to conventional stock price graphs. Rationale: with high speed connections, the range needs to extend to 3MB or more. This makes traffic running at low speeds hard to see in the graph.
2) In the Wi-Fi signal strength indicator (tray icon), provide customizable colors. The existing yellow on green is counter intuitive. I associate green with "go" or "positive strength" and yellow with "caution", "warning", or "moderate". At the least, allow for green on gray or black as an option.
Thank you for writing us.
I forwarded your suggestions to the program developer.
I hope he will implement them in the nearest versions of the program.
