able to customize bottom panel?

[Dean Loros <autocrosser1 gmail com>]

Greetings!

I have been running gnome-shell & have a couple of questions:

Where are the configs for the lower panel or is it hard-coded at 
present? I would like to run a lower panel similar to the one I am using 
in my current Gnome session or are there plans to extend to allow such 
things as Gnome-do, AWN or another panel type?
Second question: Are there plans to allow changing wallpaper, either by 
each desktop to further define each space or all change at a given time 
interval (such as Wallpaper-tray or similar)?
Lastly: I think I have the link to bug reporting, are reports encouraged 
or wanted at this time?
Thank You
