Hello, I love slip-in-slide as well, thank you for the detailed video. As you may know by now, after the trial period, Slip-in-slide is no longer free. Do you know any alternative way or an add-on that does the same but it's free?
Your gradebook is amazing and just what I have been trying to create! Thank you for sharing you. I would love to have a longer video with more details so I can implement this in my teaching and grading.
