I think it would be beneficial if the grey dropzones with the arrow had a name/title in the dropzone and maybe bordered in red to indicate that the dropzone hasn’t yet got any content. This could apply to all such zones?
Yes agree, I have asked could we target the inside of the dropzone in another thread
Only issue once you drop something in, it becomes not visible would also need a the border as you said that shows through in Elements but not in view perhaps
