Action Bar Mod - Mouseover to expand

[Aalwein]

Is there an action bar mod out there that allows you to create custom action bars that expand when you mouseover them? I am using Dominos for my general purpose needs, but i want to create an expanding bar for actions I don't use often like tradeskills, buff consumables, hearth, etc. Also, and LDB addon that would allow me to customize the list an and these items to a drop-down menu would work, too.
