I actively use CORE for serious work tasks, such as creating lessons for a digital textbook. I don't have time for systematic study, so it's extremely important for me to get answers to my questions as they arise. I quickly receive accurate responses. In this regard, I would like to wish for the opportunity not only to receive information about current features and capabilities but also to express my wishes regarding the development of technical possibilities.
