Here are a pair of add-ons for World of Warcraft that I've been using to tweak the behavior of IceHUD and Grid.
IceHUD_HungerForBlood allows rogues to follow the duration of their HfB buff, and has some coloration niceness to see how many stacks of it you have on you. This was originally the only HfB bar for IceHUD, but now it is actually a replacement for a buggier bar that is already included.
GridOnly is a tiny mod that attaches an extra layout option to Grid, "Hide default party frames." This is for people who want to use Grid and only Grid to view party and raid membership.
Both of these are hosted over on my Google Code project.
