• Fades in UI when in combat or when casting outside combat.
  
• Fades in UI when a window pops up.
  
• Fades in UI when targeting anything or mousing over anything.

• Fades in UI when typing a message in chat edit box or mousing over chat boxes.
  

Settings can be edited completely in the Options.lua file, as previewed below.

addonTable.TIMETOFADEIN = 1.0;
addonTable.FADEIN = 0.95;

addonTable.TIMETOFADEOUT = 3.0;

+Lightweight on code to stand the test of time (and patches).

Special thanks to Krainz for introducing the idea to use UIParent.
