Hi Tony:

1) The countdown is not reset when using /newtest/Y/ in the URL: no it's the desired behaviour : time is set in cookie.
2) Can you test if if not the same in master ?
3) Must be (and easy) : master don't disable it too :)
4) Use a function for this : allow update in template.js. In fact : i use a lot more 'class update' now , with just some transition in CSS : https://github.com/SondagesPro/skeletonquest/blob/master/jquery-ui-custom.css#L1272

Think i update to use addClass("ls-hidden") (to be more framework agnostic)

Fix committed to answers_html branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=21041

1: leave like 2.06 and older
4 : usage oif transition

Example :
.ls-timer-content{-webkit-transition: all 1000ms linear; transition: all 1000ms linear;}
.ls-timer-content{
height:auto;
}
.hidden.ls-timer-content{
height:0;margin:0;padding:0;box-sizing:border-box;
overflow:hidden;
display:block !important;
}
