It doesn't work for me

I’m running WIT on WordPress 3.9, no problems.

Tell me what you were trying to do and what went wrong. I’ll be glad to help.

https://projectpacks.net/1/hello-world/ shows the bug in action.

Looks like there is an issue if the animation is disabled!
Try to enable the animation by setting its interval to a value greater than zero, and tell if that gives expected results.

That does the trick but I would add in a failsafe function that if its 0 it doesn’t appear to do what it did when it was zero.

Of course!
It’s supposed to simply switch tabs. This should be fixed in the next update.

Thanks for your feeback.

This is now fixed in version 0.5.
