I love that you have the option to carrying over tags on your WP posts to Tumblr, but could you add the category as well?
I use categories as my main way to sort posts in WP, and tags to find popular things in posts (like the category “packaging” with the tag “beer”). This is truly the only thing missing from making the Post from WP to Tumblr function really quality. As it is now, I either have to wait for things to post to Tumblr, then go back and add the tags they should have, or I have to add the tags to my WP post, which ends up looking silly to have a “packaging” category as well as a “packaging” tag.
I would gladly donate a few dollars to see this implemented! Thanks!
