The patch I sent contained a bug of garbage collerctor, and more than that
it was not commented. I am preparing now a patch that contains

- no bug
- comments
- minimal code, that takes no action apart from showing the tabs.

I will resend the patch again in a few days, when I have time to complete
it, and we will discuss again about what a tab should do, in order to
implementent what you ask for a tab, etc.

See you soon.
