I am quite surprised. My personal feeling is that {{ entries:previous }} should bring back the previous entry to the one I am currently reading, and a previous entry is an older one (date wise). The next entry is a newer one.
However, I have to use the {{ entries:next }}tag to get this previous entry!
How can I force Statamic to do what want? or is it just impossible? What do you think of the way previous and next are implemented?
