Add option for post format archives

Do you mean (custom) post archives? Those are available in DW.

No, I was thinking about these: https://codex.www.ads-software.com/Post_Formats . Some kind of Tumblr-like taxonomy put in core a while ago. The permalink for the archives is /type/[format]/

Thanks for the link. I was actually aware that WordPress has added this, but didn’t think about it anymore.

Anyway, I’ll add it to the whishlist. It needs some research.
