System information (as much as possible)

Additional comments

I realize this is the current intended function, but as a developer it would be very convenient to "reset" the repeatable list table. I can see where possibly a user MIGHT have that same need a time or two.
In my case during the design of the table I realized I could add another row and rename one of the elements, after doing so, those changes were not picked up, not even the addition of a new row.

"Elements":["body","H1","H2","H3","H4","H5","H6","p","a","i","ul","li","span.company-name","span.site-moniker"],

This is the new default. Notice I changed the last two rows.

This is the result.
