The current syntax for tikzcd editor gives, when the user inputs a double arrow from (cell 1) that traverses two cells diagonally down and right from its origination point with no head
(cell 1) \arrow[rrdd, no head, Rightarrow] & ......
tikzcd's output still has a head at the bottom-right end of this arrow because Rightarrow, the later argument, has a head on it. This should be switched to
(cell 1) \arrow[rrdd, Rightarrow, no head] & ......

in order to remove the head from Rightarrow.
Thanks for your work.
