This is a new feature suggestion.
Wiki articles and Talk pages feature an [Edit] link at the beginning of each
main subheading. I'd like to see an additional [Add new section] link at the end
of the page.
If I am taking part in a Talk page discussion, and want to add a new section, I
click on the last [Edit] and add a new heading. I sometimes find that people
edit the last section, resulting in an error, that someone else has edited the page.
An [Add new section] link would let someone continue editing the penultimate
section, or let two people add a new section at the same time, without a clash
