The menu bar's Terracotta dot means a #p0 is open somewhere, but nothing tells you that, or which one. Here are three ways for the app to answer it. Each column has the menu bar above the panel. Hover the mark for its tooltip. Tick a #p0 to watch the dot and the answer go together. Quiet Mode and the switch below hide the dot.
New: the third row, on by default. The first two are as built (0.69.0). Off, the dot never shows. The #p0 items stay where they are in Today.
