Link format

Hi there, I understand that I can set the "slug" metadata to change the slug to something other than a slugified version of a post's title. Is there a way to just default to using the filename? For example, if the filename is 2015-04-05.pithy-slug.md And the title is # How to write pithy slugs in 17 steps or more! I would like the slug to be pithy-slug. Alex

If I create some folder structures in my blog's folder for additional pages, will those pages be functional on the blog? For example, will the .md file in Evil-Plan/schemes/phase-1.md be published at /Evil-Plan/schemes/phase-1? Addendum: if so, is this an accurate list of reserved top-level folders?
