At the moment I cannot delete scenes, chapters or acts that are not empty.

I agree that it is safer this way to not accidentally delete something but it is a BIG pain ...

e.g. my book has now over 100k words. that is a lot of tokens that most models cannot handle.

so I exported act 1 in an own document. But in my original, i have to delete the text of every single scene.

give me a dialog box that forces me to really confirm that I want to delete something that is not empty but please! let me do it!
