When text has hundreds of lines, it’s a pain to scroll through all the lines to reorder them. Maybe have the option to chunk the text into sections small enough that all the lines can be visible on screen without scrolling. This will be much more easier to reorder.

I already know the beginning of the text well. I would like a way to select the parts of the passage I want to be quizzed on in the drill. Don’t always want to start from beginning of the passage.
