I've been with Wolfram Research in some capacity since 1993, and have worked on the Mathematica front end since 1996. While Wolfram tolerates and even occasionally encourages my appearances in user forums like this one, my words (especially the stupid ones) are my own, and I don't speak for Wolfram in an official capacity.

Fun facts: I also like games of all sorts, and I'm a competitive Scrabble® player. I've written various sorts of crossword game-related utilities (some fun, some dead ends, some serious) in Mathematica, and consulted briefly on Wolfram|Alpha's word game content. I also contributed UI code to an open source crossword game simulator called Quackle which is quite the thing in the competitive player community.

comment How to catch the “Preemptive” evaluations from within the main loop?
@AlexeyPopkov No, I mean that the evaluation of the Ticks function, which is acting like a Dynamic in this case (even though no Dynamic was specified, it's resolved in a similar fashion), might be evaluated at any time relative to the ordering of the Shift+Enter evaluations. It might happen before the CreateDocument has finished evaluation, or shortly thereafter, or a very long time thereafter. That's why it behaves differently on different machines...because there is no guarantee...it's just evaluating when it can.

comment DeleteDuplicates not deleting duplicates
My strategy has been to fix bugs/implement features, remain silent for weeks/months, and then miss the rep uptick when the new version ships because sleep started to look better than beating out intrepid explorers for reputation. Maybe I should rethink that... :)

comment How to catch the “Preemptive” evaluations from within the main loop?
I reproduced it in v9 on Windows, but failed to reproduce it on my Macbook Air. But this behavior depends upon the ordering of Dynamic evaluations. Those orderings are specifically not guaranteed by Mathematica.

comment The shortcut for Subsuperscript doesn't work?
Documentation will be fixed in a future release (probably not in the v9.0.x cycle).

comment Context unique to each group at a specified level
This is clever in a way which I totally applaud. But it lacks some robustness. The idea is potentially plagued with issues based upon what might happen if sections get added or deleted. It doesn't isolate calculations when the notebook is closed and reopened (but that wouldn't be too hard to add). And the fact that Dynamic isn't being used here could cause unexpected issues in how these contexts change. All of that having been said, the questioner may be quite happy to work within these limitations.

comment “With” as part of the “Dynamic Interactivity Language”
@OleksandrR. I should clarify a couple of things which skew the numbers a bit; in the WRI code I was scanning, some Dynamic/With combos are hidden behind function calls which appear many times, but because I was scanning the generator code, they only show up once in the function definition. Also, WRI code uses Dynamic frequently as a means of abstracting localization strings, which doesn't look much like end-user usage. Nonetheless, I think we agree on the basic point that where you find Dynamic, you're much more likely to find With.

comment Version 9 Blue Screen or Self-Test Error on Windows 7 64-bit
We're still not sure why Windows blue-screens. Every blue-screen is a Windows bug (unless it's a driver bug, but I think this is probably Windows), and of course, we can't easily debug Windows. But WReach is right in saying that there was a naming inconsistency on one of the Mathematica5 font variants in the past which may have contributed to this mess. The installer works now by forcibly uninstalling the old font file and its corresponding registry entry. In simple terms, the installer was previously "polite" about this step...now it's "aggressive".
