Click a card in DOTV's storyboard and the detail panel slides in from the right — it covers the image and video columns, but the side column on the left stays. So looking at something full size never takes you out of the storyboard: change the prompt, switch models, regenerate, crop, trim, remove subtitles — all of it happens in this panel. This section covers the three parts the screen is made of, opening and closing it, the media area and the input bar underneath, and clicking through and then back out.
