This add-on adds a target of mouseover frame to the wow-client (the mouseover is the unit who is under your mouse-cursor).
The main advantage is that you don't need to switch your target to get this information which is much faster, especially in combat and you can still cast spells on your target.
It was originally made to help tanks (therefore the name MTLove -> Main-Tanks-Love) but it may is also useful for any other class.

• It provides a frame attached to your mouse and/or a additional tooltip next
  to the default one.
  
• It can add small counters to its frame/tooltip/default target-frame/default focus-frame, which display the number of players per class or armor type who have your mouseover/target/focus as target.
  
• It can show a bar above and/or below the frames indicating your current mouseover targets health/power status.
