I'm not sure if this will get any kudos or not but I feel Routed Systems could use more features than what's currently available, especially when it comes to segment geometry options.
What about the ability to add in shrink wrap segments? Shrink tubing or protective wiring boots are obviously commonplace in the electrical industry so it would be great if we could create these shrink wrap-like segments using an dialog box that allows us to basically create a body within the Routed Systems harness structure. Maybe something that would allow us to have adaptive lofts that can select faces or features from a connector and then create the other sketch and geometry based off a work point, plane, etc?
Something like this...
