While working in botpress and developing my bot, I noticed that the lines can get really convoluted. Depending on the converstation flow your working on, there could be many conversation flow "cross currents" that are not easily identifiable, especially if you walk away from your project and return back to it.. Perhaps identifying the conversation "flow currents" with blue and red or identifying them with arrows to help the creator easily distinguish a progress flow in the discussion with a revisting question flow..
