It was an opportunity for me to easily approach the program because it thoroughly explained the functions necessary for the basics. What was disappointing was 1. The current version and the version of the program in the lecture were different. The other functions were similar, so I was able to follow along quickly, but the way the plugin installation was done in the beginning was different from the lecture, so it was confusing. 2. If you also explained the shortcuts when explaining the functions, it would be more helpful for me to use the program on my own in the future. Thank you for the long and great lecture:)
