Thanks for your feedback. We are actively working on readability improvements everywhere.
Is your mini viewer set to transparent? Click the settings icon when mousing over the mini viewer to see. That could explain why it’s difficult to see.
We show the incoming/outgoing bandwidth on the graph so that’s better than a scale in a way. Please note my mini viewer is set to be transparent, so that’s why it looks even more difficult to see than yours.
The mini viewer is supposed to be something you can glance at to get a general idea of bandwidth usage, and click to access the main graph so that’s why it’s a bit sparse. I see your points and we will continue to gather feedback and improve the mini viewer.
