@JohnPhilpin Sorry, I’m a little unsure by what you mean by archive, but I’ll try to answer what I think you’re asking. Feed Journaler doesn’t import anything from IFTTT; it is it’s own thing that just run locally on your machine. So you will need to setup the feed configurations manually.
Also, it will be switched on (i.e. start importing RSS articles) as soon as the feed URL and journal is selected. Clearing either of these fields would stop the feed polling (a dedicated toggle to turn off a feed is something I’d like to add in the future).
Finally, given that there is no history of what was imported, the first poll will import all the articles from the feed. I suggest creating up a test journal first to import the first bunch of feed items, and moving the entries that you’d like to keep into your main journal within Day One (this is another thing I’d like to add as well).
Hope that answers your question.
