LF - Modified Default group frame addon

[Lexî]

Hi I'm looking for an addon that modifies the default group frames to add player class, health and level to the frames. I have found serveral addons suites that replace these frames however I like the looks of the default UI frames so am looking to just add functionality to them rather than replace them outright as such addons as LUIE and AUI do.

Many thanks if you know of such an addon or are able to add these things to an existing addon.
