For example, Inkscape do it with squares and diamonds
squares are soft points, diamonds are hard points.

Perhaps a script could change type of a point (or joint)

Hi Phiro,

> Michael, is it possible to view the different types of points in MOI ?

There isn't anything for that currently but it's something I would like to add in the future. It will probably be something that shows up in Join initially, like some kind of optional report after doing a Join that tells you if segment ends are tangent to each other or not.
