Hi @stefesciberras,

I am wondering if there is maybe a typo in the email address in this PR: stepehn.sciberras@mmsjournals.org -- should it maybe be stephen instead of stepehn?
Could you please also remove the empty lines between elements -- for the file to stay consistent.
You can add the element <certification type="reviewed"/> as elsewhere in plugins.xml.
The JS is added to every template. I think it would be better to narrow it to the one it needs to be added to, something like this:

if (!$templateMgr || $templatePath !== 'decision/record.tpl') {
      return false;
}

Would you mind changing this?

Not a merge-stopper, but maybe you would like to also consider the following:

• HANDLER_CLASS — the plugin registers its page handler via define('HANDLER_CLASS', 'APP\\plugins\\generic\\reviewerComments\\ReviewerCommentsHandler'); in the LoadHandler hook callback. This is marked deprecated in OJS 3.4's core and has been removed entirely in OJS 3.5. It still works correctly on the plugin's target (3.4.x), but would need change at least for 3.5 on.
  As an example, core's own bundled staticPages plugin shows the non-deprecated way: grab the hook's own by-reference $handler parameter and assign the instance directly ($handler = new StaticPagesHandler($this, $staticPage);) instead of using the HANDLER_CLASS constant.
• English-only button matching — the frontend JS locates the "Insert Content" button to attach next to via a hardcoded regex, /insert content/i. On any non-English backend locale (pt_BR, es, etc.), that button's label won't match, so the plugin's control silently never appears — a real functional gap for a platform where non-English admin UIs are common. Maybe to use tiny.settings.toolbar.includes('pkpInsert') instead -- the JS already locates the active editor instance via findTinyMce()?

Thanks!
