Hi, guys. I have a suggestion which I think could be easy to implement and very popular.
Create sequence of interactive videos where the Adaptivity setting (correct/incorrect) allows to seek to time stamp on a different video. Currently it can only be done within the same video.
1. Start playing Video 1 at 0:30
2. Fill blanks (cloze) question at 0:35
3. Correct answer seeks to Video 2 at 0:10 / Incorrect seeks to Video 3 at 1:40
This way, users could take several Youtube videos and play only the clips they want, creating a kind of storyline.
Imagine a storyline discussing Trump quotes or particular news topics. The creator could create a storyline with several Youtube videos in a sequence, with questions (or without questions if desired, simply playing the fragment of interest, e.g. 0:10 - 0:15 then automatically loading the next video in the sequence). The Branching type is not so good if you only want to play a part of a longer video.
I think this would be a popular feature, and I would imagine you already have most of the coding done for that.
Keep up the amazing work!
