You can add buffs to buff bars, which you define on your UI, and those buff bars are either your own buffs or enemy buffs.
So put the 4 buffs you need to watch on an enemy in 1 bar/container and move it on the UI where you need to see them.
The addon got videos that describe how to do that at the addon description.
