In my writing I often use a comma and the past progressive tense (I think) to make sentences more concise.

For example:

The new design was more intuitive and user-friendly, reducing user errors.

Is this grammatically correct? Are there better alternatives?

    The comma doesn't avoid using "and". Even if you'd used the alternative "and reduced user errors" it would still be required. It's just that "reducing" carries the strong implication the reduction in errors is a direct consequence of being more intuitive and user-friendly, rather than simply another characteristic of the new design.

This is grammatically correct. In fact, replacing the comma with an and will remove the validity of the sentence.

"Reducing user errors" is a phrase. It has no subject, only a verb. This phrase shows another thing that the design does. The main thing the design does is that it is more intuitive and user-friendly. The phrase shows another thing that it does as a result of being more intuitive and user-friendly, in this case. This is a very good sentence. I would say that you continue using this format because it works very well.
