I would love a book mode feature on the folders. When slightly folding, the text on your screen breaks into columns like pages on a book. This would work great in the Kindle app, play books, the bible app, and Samsung internet.
Kindle and play books already support this in settings. I dont use Kindle anymore so i dont have the app but in play books, enable 2 column layout to have the text broken up into one column on each half, and 3D effects if you want the page turn effect. This works regardless of if you have a folding device or not, but if you do have one, it will continue to work if you have the device at a slight fold. Other apps would need to support this within settings, unfortunately this is not something that can implemented on a system basis and have work with individual apps. It needs to be implemented in a per app basis by the apps developers.
It only works in Kindle in landscape. I'm talking a similar deal to the way flex mode pops up when folded. Full screen columns making your crease look natural just like a book when slightly folded.
