There has been several quality of life improvements with the new nameplates. ElvUI team and the oUF team has been putting in quite a few hours in improving both addons to support the rigorous NamePlate improvements. Personally I have been working with ls- from the oUF team for a couple months building the new NamePlates. We merged them into Development around 2 weeks ago so the ElvUI team as a whole could tweak and test them with a few other coders for this release.
The list of things we are currently working on that didn't make it. (I know. I'm sorry)
Known Issues
- Cutaway Health -> Cutaway Health / Power (This one is pushed down as the functionality of the others are far more important but it's still coming back)
Planned Additions:
- Auras -> Single Header (Buffs & Debuffs)
8.1.5 Features: PvP Classification Indicators [ Carts | Flags | Orbs | Assassin Bounties ]
Tags / Sizing / Position / Offsets / Fonts on every element.
Occlusion Checks (No more seeing enemies through floors/walls)
If you want a complete text only nameplate. It's capable.
Complaint / Suggestion Box is below.

To change the nameplate health percent etc, you can use this guide viewtopic.php?f=9&t=6 (it is the same as what is used for Unitframes )
