I'm sorry, but the redesigned interface is, in my opinion, a step backward. It's harder to use, and requires more clicks to do certain things (like editing a meta value)...
But one BIG problem is that it appears the ability to ADD an existing meta key to a user who doesn't have that meta key has been removed. Or if it hasn't been removed, I can't figure out how to do it using the new interface.
To clarify - I'm not talking about creating a new meta key. We've created a meta key, which we're assigning to SOME users (but not all). Then, in certain cases, I need to manually add this meta key to other users. Now I can't, and this poses a major problem for the way our app works.
1) Is there any way to add an existing meta key to a user who doesn't have that key yet (as was possible before)? If so, how??
2) Would you consider reverting to the old interface design?
