When I am writing a chapter I split it into scenes at the flow allows. Once I do that, I get a new card to write a title and synopsis on–a great feature. I usually use this to jot down notes for the scene. Sometimes, I will outline this way, setting up one folder per chapter, splitting into scenes, giving each scene card a title and some notes as to what that scene will contain.
Each scene has a title, so I can quickly go over the flow of the chapter in my head.
However, when I am looking at chapters fused together (scrivenings) I want to see the title of the cards for the scene and cannot, because the inspector is on the card for the chapter. With me so far? I can not see, at a glance, if things are in the right order. Sure I can read everything, but that takes time.
My suggestion is instead of the split lines being a dashed line only, that they be a wider grey line containing the text from the title of the index card for that section. Perhaps a small shaded area below the dashed line. Either will work.
Thanks again for a great product. I look forward to your next update.
