Support for categories like in OYS and OYG

It would be nice if Teacup supported posting to a category like OwnYourSwarm or OwnYourGram do. I post eat and drink posts with Teacup. They show up as Uncategorised post in my WP site. I then manually reassign them to a Food category. If Teacup supports a category taxonomy, it would be nice.
