No bug report, no rant, just a simple:
Thank you.

Seriously, it is great to see that Stack Exchange Inc. actually did put in serious efforts to improve this core aspect of quality control. And albeit many "quality control users" complained for years about lack of support, within a few days, there is plenty of helpful, precise feedback.
So, please continue on this path! And note: even in the midst of that storm that is shaking the whole community, the community users are obviously willing to work with you.
And my direct feedback regarding the UI itself: it really looks/feels "fresh", and I hope that it won't take long to incorporate the reasonable feedback, and to roll this change permanently.
Then, to underline what you already mentioned: this goes way beyond "just the close reasons". Close reasons relate to queues, and most importantly: follow up actions. And oh boy, there is work waiting for you. So, what you seriously need to look into:
- The overall workflow. As explained in the aforementioned link: the triage queue on SO is a nightmare. Fix that.
- One way to get there: improved education. You could prepare an education package that includes 50 or 100 questions for people to train with. Hand selected questions, with manually written explanations for each one of them!
The one thing I ask you folks to remember: stay agile! Don't wait too long in order to release the perfect thing. Rather roll early, but be around to constantly fix bugs and improve features frequently!
