For a future "feature" it would be helpful for the identity of the "strongest signal" to be available somewhere on the display. At present, it doesn't appear that the node information is supplied regarding which station has the strongest signal on the display.
The strongest signal can jump between nodes each moment so I'm personably not sure how useful it is to show that on the status page, and it would increase logging (space) requirements to do so on the logged history pages. There would also potentially be a decrease in the update frequency of the indicator if we have to parase out which device is the strongest at that moment on the real time page.
