Hello, can any 1 tell me a good addon for the default action bar that can move it coinfig or make a new bars for it and support button facade:S tthx.

Bartender (available here).

Macaroon! (available at WoWI).

Bongos (available here I think).

Dominos (available here).

I know this addons but what i need is to Customize my default action bar blizzard action bar.

I don't believe there is or is many addons that will allow you to customize the default blizzard bar.  IMO your best to change to one of the replacements as you can configure them many different ways with more options. Bartender4 is what I use and I'm am happy with it.  Now if you want to find one that does what you want your just gonna have to look through this list of addons. I did find this though.
