Been using adobe illustrator for decades now and there is one feature that has never been implemented that every other software has and adobe still does not. Smart dimensions, I'm sure every artist that has ever used illustrator for production purposes would like this feature added. Corel has it, all CAD applications have it, Illustrator is pretty much the only vector based design software that has not implemented this yet and I would love to see this added. There are plugins for illustrator to do this but they are extremely expensive, so if a 3rd party can implement this I'm not sure why Adobe cant. Hotdoors Cadtools is a perfect example of the feature set I think any production artist would love to see built in to illustrator and would be an absolute game changer for anyone in the signage or large format printing industry.
