First of all, Charles, if you're reading this: thanks for writing the FeedWordPress plugin. I know that writing a free WP plugin can be a thankless task-- but I really do want to compliment you on your great work in creating this.
The problem that I'm having is this:
I have my feeds set up to import and be saved as Drafts (so that I can tweak them before they're published.) But, what happens is, if I have previously imported and then Published an item -- and then if the original source item is edited on the original source site -- then the next time I import the feed, the item that *I* published gets OVERWRITTEN and set back to "Unpublished."
Granted, I can use WP revisions to manually go back and restore all posts that get Unpublished, but that can be a real pain to do every time feeds get imported.
I don't think FeedWordPress should Unpublish entries if they were previously Published-- I'd MUCH rather get "duplicate" Draft posts added when the original source gets revisions, rather than overwriting anything I've already done on my end.
