nicer/customizable names for tabs in url

Issue Summary

First off, I love this module!

But, a request:
In the URLS, users see stuff that looks like:

http://yourdomain.com/path/to/node#fieldgroup_tabs-4

That fieldgroup_tabs-n part looks kind of clunky, especially if it ends up in an url bar.

Is it possible to add a feature that lets you customize it, or at least use something based off the title of the tab or something? Something that would make a "prettier" url?

Or is that feature in there, and I'm just dense (I've been dense before.)
