Feature request: disable tab

[sudodoki]

Hi!
Thanks for the project, finding this handy!
Have a usecase when I need to disable tab from set of tabs on some condition so interested if this is a decent usecase/feature request.

Just ended passing a className from Tabs to resulting dom sudodoki@9a4bf7c#diff-be3075e36834673d63173d3497c17afcR93
