Is there a plugin that can help create walkthroughs for javascript apps / sites?
If not, (I can't find anyone through Google, although I could swear I knew at least one), is this a good idea (for a moderately complex application)? How does it compare to screencasts? What is your best practice if you have to do this? And in general terms, what are some ideas on how to do this.
Thanks in advance.
Edit: As an example, something like this I just found.
