Lack of MRU tab order for Control Tab behavior is just one way in which I've been becoming increasingly unhappy with UI developments in Chrome. In looking into it, I found a developer's blog entry explaining that it is a design decision; they don't see how MRU fits into their conception of work flow or how to achieve a "perfect" implementation (sorry, I don't have the URL for that entry at hand).
With... v6, I think, of Chrome, they changed the padlock / SSL-TLS designation appearance, to my eye making it less clear when a site is secure. Such UI paradigms take a long time to establish themselves in (non-technical) users' minds, so particularly for security-focused ones, you shouldn't go changing them willy-nilly -- it defeats their primary purpose.
(Separately, their own properties break their secure channel at times by including non-secured resources.)
Rightly or wrongly, in the lack of a more thorough analysis, this has my intuition tweaking. I'm starting to feel jerked around by decisions such as these. (And a corresponding one-way nature of communication, or outright lack of communication, on the matters.)
I know, "looking a gift horse in the mouth". Keeping engineers busy engineering as opposed to "'splaining". And this is a feeling, not an analysis. So I won't claim the high ground, here.
OTOH: Chrome has keep a family member's older laptop functional, where otherwise it probably would have been retired (Opera's recent speed improvements might now also compensate, but a number of sites they use fail in Opera while working in Chrome.)
