We use comments extensively in certain parts of our confluence instance to record customer interaction.
Therefore we already adjusted the order of the comments in a way that latest comments are displayed topmost instead of standard sorting.
Now users requested to also move "add comment" field to be moved above the old comments, so that they will have to scroll less in order to add a new customer interaction.
How can we make this change? I assume it can also be done with custom HTML/JS?
Appreciate any hint! 
Happy Confluence!
