Just Showing off:
This link shows a HTML5 Timerline using jQuery (no plug-ins).
So why doesn’t Lectora have a timeline?
Looks like a nice plugin. Actually we are talking about adding a timeline. What are the main things you would like to use a timeline for? I know it might seem obvious but it helps us when we hear your take on it, you might come up with some use cases that we did not think about. Thanks again for suggesting a timeline it will boost the priority with our product management team (I will make sure they see your post).
