Always display connection points / increase size of connection points
In Visio 2016, connection points are only visible under certain conditions:
> Connection points become visible when you try to connect one shape to another. You see a shape’s connection points when you hover near the shape with the Connector Tool or drag the endpoint of any connector or line near a shape that has connection points.
In older versions of Visio, connections points were always visible. Please add an an option to always display connection points.
Additionally, when the connection points are visible, they are difficult to see, even when zoomed in.
Increasing the size of the "grey square" and "X" symbols used to denote connection points would solve the problem.
