Detailing is not on your list, Brian, but we have two shortcomings:
1) Explode extension lines do not perform hidden line removal for the extension lines. The hidden view display algorithm needs to be performed for shaded view explode. This appears to be a simple specification oversight.
2) It is high time shaded section views capabilities are added as an enhancement.
I use the detailing package for presentation level documents. These are the top two limitations I find that cost me significant effort to secure a reliable work-around, both of which require view duplication and accurate overlays of two views.
