WME should indicate when a segment end overlaps but is not connected

Firstly, take a look at this image:

As per the screenshot, these segments are NOT connected but it looks like they are. It should be obvious in WME when segment ends are close but not connected. In this screenshot, the little dot on the green segment looks like there's a junction node there, but in reality, there is not.

Please make it clear that segments aren't connected when they probably should be.
