Last night, I create a user test for the recently updated widgets prototype. About 30 minutes later, I had this super awesome video of a real person using the prototype and talking about his thoughts and experience: (beware the loud cough at the beginning)
This one went very well. And it seems that the idea of dragging widgets into sidebars is engrained in existing users. I’ve even caught myself doing it a few times, and I built the prototype specifically to avoid that interaction. It makes sense, as dragging widgets into place has existed in WordPress for over 3 years.
