I really haven't done that much with Polaris. I tried doing a search in YouTube but really didn't see anything more advanced. I think the developers have a website, maybe they'd have something. I'm sure a google search could find them. Also, it's a round about method but check out QuickOffice. If there's some advanced information about QuickOffice, the same kind of thing can probably be done in Polaris, they're very similar.
As for S-notes, I thought I was pretty knowledgeable but there's so much on YouTube that's taught me a few new things that I'd recommend just doing a search there and you'll soon know which contributors have the best. Sorry I'm not more help.
