Why do you change the subject of discussion ? saving and restoring window configurations concerns other type of tab, not this one I am talking here.

How do you communicate to the tab what the "something" is?
execute 'grep -i foo *' in background , example

This is the standard buffer switching functionality.
I know how to commute a buffer. In this case of tab, I want the show event to commute to a given buffer.
What sense does it make to have a hidden tab change color? And what

kind of event is this in your nomenclature?
Tabs should register a callback for an event , for example, when i/o arrives in the given process...
So far I'd only insist that saving and restoring window configurations

should be done with the menubar rather than with a tab. I never ever
use toolbars but I think that mail handling routines using the toolbar
(could) do such things routinely (inform of new mail, kill a buffer and
remove the associated button when mail has been sent , ...).
Quite so, you can do this functionality using only M-x and calling lisp functions. Or menu entries. But I am sure most people would be happy to be able to define a tab that shows a 'grep process.
