LoseControl makes it easy to see the duration of crowd control spells by displaying them in a dedicated icon onscreen.

Features:

• Displays duration of all CC spells and abilities. Also supports silence, disarm, root, snare, and immunity effects, and a few PvE debuffs as well.
  
• Can display icons for player, party, focus, target, and arena enemy frames.
  
• Icons can be moved, resized, and made transparent.
  
• Compatible with CooldownCount/OmniCC

You can see a quick demonstration video here.
Note that the LoseControl icon is in the middle of the screen. The rogue does a Sap->Cheap Shot->Kidney Shot combo, and then I trinket.

New in 3.32:
Fixed bug on startup when updating settings from older version.
Fixed possible bug with tracking options on non-English clients.
Immunity tracking no longer tracks self.

Known issues:
Psychic Horror disarm effect is disabled to prevent conflict with the horrify effect.
Perl and XPerl support doesn't work with 3D portraits (strata issues?).
Unlocking frames does not show arena enemy frames if they are anchored to Blizzard frames (because they don't exist unless you're in an arena).

To Do:
Optional priority for different types of CC.
Options profiles.
Button skinning.
Improve OmniCC support to work with all strata levels.
