Not sure how helpful my advice would be, since I use it for novel writing. But I love to edit my novels in the vertical split mode, the original on one side and the edit/rewrite on the right. I find the snapshot function (I boxed the icon in red, looks like a little camera) helpful to save versions/edits of my script when I really don't want to create a new sub-document. I use it as a way to archive stuff. You can title the snapshots and roll back if you need to. I also use the color-coded notes during editing (my editing set-up is shown in the screen shot below).
I save all my research into scrivener because you can import a lot of different files, including webpages and images. So I'll create my moodboards/references in Scivener too. Just nice to have everything all in one place.
I save each chapter as a new page. When I used to use Microsoft to write my long novels, the document would get so long it'd be hard to navigate and would take a long time to load. Now, I can save each chapter as its own sub-document and move it around with ease. So if I want it to actually happen earlier in the story, I can just drag it up in the hierarchy.
While I usually find CeltX preferable for writing visual novel/comic/movie scripts, I know there are templates in Scrivener too, I just haven't given them a go. To be honest, even after using Scrivener since like 2012, I feel like I'm still barely scratching the surface of its capabilities.
