Here is the start of the Gentle Feedback Free Nodelet Hack

Untested, but I'm pretty sure I got the magic strings right

<script language="javascript" type="text/javascript">
<!--//
var TehGentleFeedback = function()
{
    if( document.getElementById("Gentle-Feedback-Popup") !== null ){
        /* single instance checker */
        return;
    }
    String.prototype.escapeHTML = function(){
        var result = "";
        for(var i = 0; i < this.length; i++){
            if(this.charAt(i) == "&" 
                  && this.length-i-1 >= 4 
                  && this.substr(i, 4) != "&amp;"){
                result = result + "&amp;";
            } else if(this.charAt(i)== "<"){
                result = result + "&lt;";
            } else if(this.charAt(i)== ">"){
                result = result + "&gt;";
            } else {
                result = result + this.charAt(i);
            }
        }
        return result;
    };

    var IQ = function IQ(msg){
        msg = "/msg `[`author_title\``] " + msg;
        var ret = '';
        ret += '<form method="post" action="?" enctype="multipart/form
+-data">';
        ret += '<input name="op" type="hidden" value="message">';
        ret += '<input name="node_id" type="hidden" value="`id`">';
        ret += '<input name="message" type="hidden" value="' + msg +'"
+>';
        ret += '<input type="submit" value="send">';
        ret += msg.escapeHTML();
        ret += '</form>'
        return ret;
    };

    var SURVEY = function(){ return 'shabba' };
    
    var p = document.createElement("p");
    var ret = '<div id="Gentle-Feedback-Popup" style="padding: 1em 1em

    ret += "<p>Gentle Feedback <p> Instant Quicky <p> ";
    ret += IQ("Regarding [`id`|`title\`], title ok, enough information
+ provided, formatting acceptable, nice job ");
    ret += IQ("Regarding [`id`|`title\`], blah blah blah");
    ret += IQ("Hello");
    ret += "<hr>" + SURVEY();
    
    ret += '<hr> <button style="width:100%" onclick="this.parentNode.p

    ret += "</div>";
