in reply to Free Nodelet freed

Add the code below to your free nodelet and you'll be able to toggle between collapse all and expand all in Recently Active Threads. You can collapse them all, then expand only the threads you are interested in with the (+/-) link for that thread. Collapse_all is very fast, Expand_all takes a moment or two.
<script language="javascript"><!-- var expandState="expanded"; function toggle_all(){ expandState = (expandState=='expanded') ? 'collapsed' : 'expanded' ; var elements = document.getElementsByTagName('ul'); var elnum; for(elnum=0;elnum<elements.length;elnum++){ var lb = "\x5B"; var rb = "\x5D" var el = eval("elements"+lb+"elnum"+rb); el.className = expandState; } } //--></script> <p> <a href="javascript:toggle_all()">Expand/Collapse All</a> </p>
Thanks cLive++ for the evil string eval.
