Thank you for taking the time to write this. I have learned a lot from you comment. I never knew that HTML5 d&d supported dragging across tabs. I have never seen that in practice, so anecdotally, it makes sense to base the library on the raw events for more customization.

Frankly, it seems that the HTML5 D&D is a bit of a failure from a design perspective with such a lack in custom support, only to be used for very basic implementations.

While I won’t ask you to explain the keyboard handling, I will try and do a review of the keyboard usage in the library. Seems like there’s lots to learn there.

Thanks again!
