-        Notice: The newest Notebook.ai release is adding the ability to create your own link
-        fields, which includes a rather large migration of all existing link fields into a new linking system. 
-        Links that haven't been migrated yet can be seen below this message; links on the new system appear above.

-        Thank you for your patience during this large rewrite! This notice will automatically disappear after the
