KeyShot's workflow and processing are so much faster than everything else out there. The only thing that chews up a lot of time is the creation and adjustment of custom materials.
It would be great to have high quality material libraries bundled with the program or available as (modestly priced ;-) separate purchases.
For example "Jewellery", "Plastics", "Nature", "SolidWorks Compatible", etc.
You would create additional income streams AND make us time poor users much happier!
I think this topic was discussed loads of time before at this forum
