Design goals

Simple. Lightweight. NeedToKnow is for minimalists.

Simplicity of function

  • NeedToKnow is a timer bar addon.
  • NeedToKnow is intended for your most frequently monitored abilities. NeedToKnow is for your rotation. It's NOT intended as a general buff/debuff addon. If 4 groups of 6 bars is not enough for you, you want a different addon. You might also want to rethink your UI.
  • Features should be opt-in, not opt-out.

Simplicity of appearance

  • NeedToKnow is intended to show you the most important information—and ONLY the most important information—at a glance. The idea is that the only things you want moving or taking up screen space are things that are important.
  • The bars don't move locations so that you always know where to look to know when you need to refresh a DoT or short-term buff. You don't have to search through a stack of bars to find that one important one.
  • Cosmetic features should reinforce, and not distract from, the visibility of most important part of a bar: its length.


  • There's no reason a minimalist addon shouldn't have a minimal effect on memory and CPU usage. CPU usage in combat is the most important metric.

Simplicity of configuration

  • Users see this a significant feature, especially compared to addons like PowerAuras or ForteXorcist.
