All of that sounds similar to things we have in Ubuntu, though it's not
immediately clear exactly what you mean. But in any case, I don't think
there's anything Unity specific about that. I would take that to
ubuntu-desktop@xxxxxxxxxxxxxxxx instead.
If you do, please try to provide more specific examples. It was very
difficult to understand what you meant.
