I guess I would like to see it become faster and more user-friendly. I think CPLEX is very flexible for different languages so maybe they can provide more detailed documentation on how to format a model in CPLEX, and how to output the solutions. It could provide some examples, some specific standard examples, which I think would be very helpful for beginners. I would also like to be able to receive feedback on why sometimes a problem gets solved easily and why sometimes it does not. If we had more insights into the problem structures we would know if we need to use the back end for some problems, or if we need to use other software or develop our own algorithms.
