Opinions on what is still needed in CAD Software for 3D Printing

I'm just trying to get some opinions on what features are still missing in typical CAD softwares that could make our lives a lot easier when it comes to 3D printing. I think it would be very useful if it could help separate bigger pieces into smaller pieces, that could connect to each other after the items are printed out. Would allow for larger printouts on smaller printers.

Any other ideas/opinions?

I think the overall programs just need to become more userfriendly for those that aren't experienced CAD users. More and more people are starting to design for 3D printing, that wouldn't normally have a use for CAD. There needs to be more basic features and tools to help those of us that are less experienced design things.
