As I've already mentioned, the "unimproved" UI last used in the 11.3.7 was perfectly fine, and there was no need to "improve" it in any way.
Realizing full well how much time and energy you have given by now to the various UI iterations, and that, in the face of all of that work already invested, it might be difficult to just accept that all that was for nil, but would it be possible to simply return to how things were before all this started? For me at least, all of the different releases/variations to fix what wasn't broken in the first place are proving distracting, problematic or just plain ugly -- I have a very hard time looking at the most recent release, the 11.4.5rc1, with outlining (unnecessary) and text both much too heavy, especially with sites with many permissions.
Can we simply return to the original, "unimproved" one? Or at least give us the option to use that one? Or if it is impossible by now to return to the "original," can you please just stop at the interface employed in the latest stable release, the 11.4.4, which, although I still prefer the 11.3.7, is for all intents and purposes good enough?
