As a helpful tip, I am able to workaround with disabling the show reply button, and showing the entire commen tree automatically via the javascript below. Just add the code snippet to the footer.
Unfortunately I can't use this awesome extension (yet) since the original post still displays linearly below, and no easy way to hide them. If the extension can allow the option to display replies only in the comment tree, that would be a pretty useful feature I think.
# Auto show Evergreen comments every 1.5s (If enabled)
<script type="text/javascript">
function autoShowEvergreen() {
var elems = document.getElementsByClassName("Evergreen--show");
for(var i=0; i<elems.length;i++) {
if( elems[i].tagName.toLowerCase() === "button" )
elems[i].click();
}
}
window.onload = function(){
setInterval(autoShowEvergreen(), 1500)
}
</script>
