I'm embarrassed that "drag to orbit. The page scrolls past." has escaped my notice til now, yikes. I have an entire skill [0] devoted to eliminating this kind of ui slop, sadly it missed this one.
The landing page is very old at this point and definitely needs a freshen-up. The exploded view feature was built before fastener support, so you are absolutely right about that. Sawdust already can do much better, here's the same Sawhorse project's guide [1], take a look at the video there to see the fasteners driven in with respect for actual physical collisions :)
If you do try the product out you can easily submit feedback through the MCP or via the ui chat, I get paged for every feature request and love working on things users actually want. Would highly value any additional feedback.
