Is there any way to print flashcards in the order in which they appear in the text?
Not that I know of, but if you save the words in that order, you can probably preview that list, copy the contents into a spreadsheet, add a numbered column and sort by reverse order - the word you saved first appear on top of the list, and so on.
Now, this isn’t the most practical way. I’ve mainly used other tools to extract word lists. Mostly, the words appear in the proper order.
