Implement a FormHandler form editor

Allow users to design a form that updates a single row. Use this to

edit rows
as a modal, a separate section, or as an iframe
rapidly flip between rows using submit / keyboard navigation
learn from data already typed to ease the process of filling the form
support automated columns (e.g. updated time, editor)

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
