I use OmniCC + ElvUI and am used to the tenths of seconds kicking in under 3s. Would be great if this would an option I could choose in the UI. Currently I'm just manually changing the threshold in Interface\AddOns\OmniCC\core\timer.lua file.

(for anybody reading this now or in the future, to change the value of this setting, change line 35 from 5500 to 3000)
