Lightweight diminishing returns tracker for self, friendly and enemy players. You may also toggle tracking for PvE. 

About
Diminish attaches icons to unit frames or nameplates, displaying time left until a diminishing returns category expires for that unit, as well as how far the category is diminished. (Green border = 50% duration, yellow = 25%, red = 0%) You can filter which categories/unitframes to track for and more in the settings.

In PvE mode, stuns and taunts are tracked for all mobs, meanwhile roots are only tracked for elites and quest bosses.

Configuration

Type /diminish to open the options panel.

DR icons for each unit frame is separately configurable. Certain unit frames are default disabled for tracking or only enabled for certain zones. You may also skin the icons using Masque.

If you have minor experience with scripting, you can also open the file "Diminish/core/config.lua" to change font settings for category text and also change indicator colors.

Notes

• Diminish not working with an unitframe addon? Go to options and enable "Anchor to UIParent", then position the icons wherever you want. For Party frames, try disabling "Use Raid-Style Party Frames" under WoW's interface options instead. Submit an issue below if it still doesn't work.
  
• All timers are deleted if you die, so if you instantly resurrect the timers may sometimes be wrong.
• Does not track knockbacks. (Too unreliable)
