At the top of '1rambling.org and other files is a line like this:
#+STARTUP: showallThis sets initial visibility. See also Summary of in-buffer settings.
The STARTUP line is placed at the top so that it will remain behind when sprints are moved from '1rambling.org to '2rambled.org.
When using '1rambling.org, it is convenient to widen and end-of-buffer to continue appending to the chronological log. Therefore in-buffer settings are placed at the top of the file, not the bottom.
