There are existing options that can help to remove the clutter. In the Options menu go to "Social Options". Under the Group Effect Options there are two choices:
- Only Show Dispellable Effects
- Only Show Effects Cast By You
It was common to enable both of these during full fellowships. These get rid of a lot of buff/debuff icons that you don't really want to see since you can't (or don't want to) do anything about.
