This can be considerably reduced by hitting the I've checked all of these button".

But I'm observing myself mostly doing a simple reload instead...

My theory is that my lazy self si to reluctant to scroll down to this bottom!

I decided to pimp up the CSS of the button in the Free Nodelet settings to stay fixed at the top.

There is a CSS2 and a JS solution, bot work in my FF:

<style type="text/css">
<!--
#nodethreads-foot * input[name="viewedNewNodes"] {background-color:ora
+nge;position:fixed;top:20;left:500}
-->
</style>
[download]

<script><!--
function move_RAT_checked(){
  var forms=document.forms; 
  var f,b,s;
  for ( f in forms) { 
    if (b =forms[f].viewedNewNodes){
      s=b.style;
      s.backgroundColor="orange";
      s.position="fixed";
      s.top=20;
      s.left=500;
    } 
  }
}
move_RAT_checked();
-->
</script>

Actually I hate fixed HTML-areas since they slow down scrolling, maybe I will switch to postion:absolute

<style type="text/css">
<!--
#nodethreads-foot * input[name="viewedNewNodes"] {
     background-color:orange;
     font-weight:bold;
     position:absolute;
     top:200;
     left:10
}
-->
</style>
[download]

maybe I will try to bind Control-r (Reload) to this action.
