Two panes of the same size, A over B. The selected pane's tag is filled and its pill says PTT; the pane with the call is green, with the caller and the RX pill on row 2. The selected pane has the arrow under its letter. Under the panes: the state line when there is one, then the last calls, each with its pane's letter. Details: dual-watch.md.
