I don't mind the front end being updated so long as we don't lose functionality in the process. Nvidia Profile Inspector is an absolutely essential piece of software for me, and I regularly use it to force games into behaving the way I want them to. It's the single thing I miss most when using AMD cards, as there's not even a remote equivalent in terms of functionality, with similar programs like ATI Tray Tools having disappeared a long, long time ago. AMD's driver revamp came with many positives, and the "new" Radeon software is very slick, but Nvidia's stability (in terms of the software package) has resulted in an extremely mature ecosystem. Years go by and nothing changes, but that's also a good thing in many ways, especially if you play a lot of older games like I do. Those typically require at least some wrangling to get running right on modern systems and NPI is invaluable for facilitating that. The same wealth of tweaks and settings just isn't available on AMD cards, and some of those that are have been pretty hit and miss (in terms of working at all) in my experience, in particular when it comes to older titles.
So yeah, jazz up the control panel interface all you like, but leave the back end alone. That part simply doesn't need fixing.
