raid target icon button bar

[Aalwein]

Is there any mods out there that put the raid icons into a button bar for easier use? I just want to have a row of buttons I can position near the target portrait that will let me click once and have it mark my current target.

The mod you are looking for is called BananaBar (I know the name is pretty stupid).
You actually have to CTRL+Click on the icons to assign the icon, regular clicking will switch your target to that icon. Another wonderful feature of the addon is that it shows the number of people currently targetting each marked target.
Here's a link to the curse page with banana bar
