I use Readability to isolate just the text when I save web pages. I then print and use the Save to EagleFiler PDF option. I’m finding that if I do that, it will import before the web page is completely printed. It seems to only get the first page. In contrast, the Save to DEVONthink Pro script does get the whole document.
I’ve been working around this problem by printing to PDF and then dragging the resulting file to EagleFiler.
