I'm working my way through setting up a new website for a client and I'm having issues with how I think creating posts should work.
I went and clicked the create post button and when I went to change the category, I see what is in the first screen shot. Originally I was able to add the Gallery category, but I've never been able to figure out how to unset the release category.
I also don't see the normal upfront "draggable elements" until after I've published the post. Simply saving a draft doesn't seem to bring it up. That seems a bit... unfortunate to me.
