Summary: I would like to know of some way to tell Calibre that I want articles from Instapaper as a plain ol' e-book (with chapters at the articles) instead of a periodical.

I use Instapaper together with Calibre for sending my articles to my Kindle. They arrive in the Kindle periodical format, which has different functionality than a standard e-book. Most notably, the Kindle Paperwhite "Time to Read" function is not implemented for periodicals. You do get a standard e-book if you manually download the ePub from your Instapaper reading list, but that ePub unfortunately doesn't contain any images (which are sometimes needed for context).

If don't know exactly where to put this thread - Recipes, Devices and Conversion all fit to some degree.
