When copying and pasting json (tags at least, haven't confirmed View components), the paste method when pasting json that defines things that already exist is to merge the json into the existing. This, most of the time, is not what I want to do; I copy the json out, edit it, and want to overwrite the original definitions. It would be super helpful if there was either a setting in the designer properties or a prompt when you're pasting json to select which method to use.
