Just some general comments
- not being able to edit the date is annoying, everything else on the LHS is editible.
- when editing the author name, having to switch to the right panel is annoying
- having the have Title - abstract - sub heading - content, instead of allowing Title - subheading - content is an annoyance.
- trying to reflow paragraphs by introducing line breaks is leading to some confusing behaviour - could be good to do some user testing on how people write, and identify where they get confused.
