Often when building a flow chart, I want the nodes in the chart to be similar with solid arrows from one to the other. While I’m building the chart, I like to add sticky notes and attach them to the node for which they apply. However, I like to use a curved dashed connector with no arrows so the sticky doesn’t look like it is part of the flow.
I image allowing different preformatted connectors in the quick access tool part.
Or perhaps right clicking on any connector and having some connector templates to pick from.
