Three things nUI 6.0 will do to address this...
- Shareable action bar profiles: It will be possible to create a "profile" for your action bars in 6.0 and save the profile. You can then copy that out of your saved variables file and make it available as a plugin to nUI with easy. I will be creating a template players can use to do that with. Once that's done, then it will be possible to create a library of pre-defined action bar setups players can pick and choose from as well as different bar sets for multi-spec and different playing roles (i.e... PvE versus raiding, versus BG, versus Arena bar sets)
- Player profiles: In 6.0 I am going to move the saved variables from per player back to account-wide which means you can save custom setups and have per-character layouts. The layout engine will allow you to create class-specific UI designs for nUI and like bar profiles, this will allow you create downloadable plugins players can pick and choose from to customize their nUI layout on a per character basis. And, as before, for dual specs, you can change layouts on the fly... so if you switch from DPS to healy, you can change you UI to a healy friendly layout versus a DPS layout.
- Integrated GUI layout tool: My goal is for all of the options we currently hand edit in nUI's layouts to have integrated GUI tools to customize. This info will be saved in the saved variables file as a library of UI elements which, again, can be easily carved out to create custom downloadable UI elements. This means that it would be easy to create a unit frame that's "best" for a DPS and another that's best for a healer, a tank, etc. and then build up a UI from that. These, too, would be shareable between players.
Hopefully, those three elements taken together mean that the nUI user community will be able to take their creativity past just the artwork and extend it into the entire layout/interface and create their own looks and layouts for nUI and share them. For "newb" players, this will mean they will have the option to download one of several healer layouts for nUI and just start playing without having to know how to do it themselves, set up action bars, write macros, etc. As their skill improves, then they can use nUI's built in tools to tweak their layout and, perhaps, eventually start contributing to the library of layouts.
Big goals... but that's pretty much what nUI 6.0 is about (besides adding the missing features and fixing the FPS bug)
