Hi. Love the plugin. I have a couple of suggestions for features. One would be to be able to specify a custom ID for the tab so that the tab could be visited via a URL like /page.html#nice-tab-name instead of a URL like this: /page.html#tabs-13-0-1. It would be a much more user-friendly way of doing it.
I'm imagining you could specify the ID in the tab shortcode like this: [tab name="New Tab" id="nice-tab-name"][/tab]
