Add help system with IntroJS

[sisi-huang]

Create a step-by-step guide for a website and highlight each step with a box

Couldn't test it because I get an "ERROR: could not find function "introjsUI". Is there a library(...) missing or a custom JS file?

[sisi-huang]

Sorry, my bad, you're right, need to load a new package "rintrojs" in app.R file

[internaut]

Can you please fix that and also add the dependency to the list in README.md?

[sisi-huang]

Sure, will do

Thanks, works now!

I really like this visual tour! However, I think it shouldn't be run automatically once you visit the site. That would be annoying for users that already know the application. It should run on request, e.g. once you click on a button. I think a button on the top right would be good for that. Also, the "Welcome / Get Started" message at the beginning should give a hint about the availability of the visual tour.

Also, most things require a little more explanation. For example "Fix all the arguments or not" is too brief. A little note on what fixing an argument means should be given. Most of the other help text require a little more elaboration, too.

"Switch to diagnose tab" should only highlight the diagnose tab, not both tabs. Additionally, it should switch to the diagnose tab afterwards automatically. Otherwise further hints in the tour are not displayed properly.

Some hints are shown outside of the display window.

It would be nice if the actions that are displayed (e.g. "check out the design code") are actually triggered (e.g. automatically opening the code panel).

Would be glad to hear feedback from others (@clarabicalho ?) since I was not involved in the initial idea about the visual tour.

@internaut thanks for your detailed suggestions.
OK, I'll put another button on the top right to make it clear.

Sure, I'll add a hint into the "Welcome / Get Started" module and make the tips for each step more precise.

As for "Switch to diagnose tab", I'll check it out as well.

To be honest, I don't think it can be trigged, it only changes with UI, but maybe there are other solutions, I'll work on it also.

Thanks, like it much more now when it doesn't start automatically.
I moved the tutorial button to the top right.

I'd still like to get some feedback on the tutorial texts before I merge it into master.
