We requested some custom work for the Blog module. We wanted an extra field for Event dates, which should be displayed frontend over the publish date. And an extra option in category to sort by this Event date. Ihor gave his own input rather than just plainly coding my request, which is great, because a good customization takes some discussion beforehand. I'm very pleased how the customization turned out. And it was ready within 3 days, which is very fast!
