Yes adding a unit frame so we can stop using grid, pitbull, or xperl would be great. I agree that the current hp frame in jamba works for some but in pvp it is lacking some features. I certainly do not know how difficult it is to develop unit frames like the above mentioned but if we had something that was clickable and more customizable all inside of jamba it would be awesome.

Main features
-size of each item and the entire window must be customizable
-ability to add or remove unit picture
-color text or bars based on class or not
-banzai aggro alert (red ring around unit targeted)
-cast bars with text option
-the health and mana need to update much faster than the current jamba option does
-clickable so we can use it as a complete replacement for unit frames
-track specific buffs and/or debuffs

the current raid frames that blizzard implemented are pretty good so a copy of those would be a starting place. basically a cross between grid, blizzard, with some of the options of pitbull.

Thank you
