Plus in create button needs to fade when disabled

[david-crespo]

Should be a one-liner.

Not related directly, but the plus icon should probably replace "add" and "attach"

[david-crespo]

I kind of like being explicit because those actions have different meanings. "Add" actually creates one while "attach" only lets you pick from existing ones. Maybe that distinction is not that important or will be conveyed anyway when you try to do it, so you could be right. In any case, I'm not sure the icon being there justifies taking the verb out of the button. (I'm not worried about screenreaders because we can make sure the right verb is there regardless.)
