I had to rearrange the comments template for a current project, essentially flipping the comments form so that it was above the comments list. The only solution that I could figure out was to copy the comments.php file to my child theme folder and edit it such that the form code was pasted above the list code.
Is this the correct approach for now? Or are there hooks for these two components that could be reshuffled in a child functions file rather than directly editing the core file?
