Creating a category was a secondary desire, but just to be clear, I can't figure out how to create a new category. I can create a Tag, but that's a sub-category of the initial category, TAGS. I can't create a new category called NEWSLETTERS or something. As far as I can tell, this isn't possible.

Besides, due to the FETCH METADATA FROM SERVER feature (which is very useful, don't get me wrong), I have hundreds of tags. A tag labeled NEWSLETTER (or whatever) doesn't seem quite right, given the seeming intended purpose of tagging. It seems like tagging was meant to separate books into categories based on topic. NEWSLETTER is more of a format (not file format; more like a publication or reader-consumption format), not a topic. Given all that, a tag labeled NEWSLETTER wouldn't stand out from amongst the other tags the way I'd like it to.

As far as the sorting being clunky... Calibre doesn't keep the newsletters in chronological order unless I arrange my ENTIRE Calibre collection by PUBLISHED or SERIES... hardly ideal.

I think it might be useful if CALIBRE included a PUBLICATION FORMAT category (or something) that users can then create sub-categories for (newsletter, novel, textbook, periodical, whatever).
