Quick question: does the scraping window need to stay focused to work, or can I do other things and let it continue scraping in the background? Running on a Mac, if that makes a difference.
The scraping window does not need to be in the foreground to work, but you should not minimize it either. Doing so may cause webpage features like lazy-loading and scrollers to not work properly.
Usually I just leave the scraping window in its maximized state, and drag it off-screen to the lower right. I leave just a tiny sliver of it visible on screen so that I can check on it. When the scraping is done, the window will disappear.
