I would like to see an option under Display Settings for setting edges that are tangent to each other as dotted or phantom lines, much as SolidWorks does. I have this set in SW all the time and is a sure tell that edges that I've intended to be tangent are tangent, and if they are showing up solid, they need my attention to see what happened.
