Suggestion for Edit Mode in Outline

In edit mode for the book outline if you have multiple generations it can be annoying to try and pick the best pieces between each generation and copy and paste them into one. This is because when ever you move from one generation to another, any changes you have made to that generation disappear.

Additionally when you scroll down and then switch to another generation, when you come back the scroll wheel returns to the top of the page making it particularly annoying when editing the later sections of the outline.

Not a major issue but would definitely make the process a little bit faster and easier.
