Yup - I totally accept that. I just put that idea out there as a pipe dream, in case someone had an idea for implementing it, but I am not passionate about it.
I know @nbianca succeeded in respecting the cursor position when inserting canned replies. This fix has been a huge time saver and much, much appreciated on my end. More pipe dreaming, I am sure, but I wonder if it could be possible to do something similar with section headings, e.g. provide a link next to section headings to edit the post and take the cursor directly to that section.
