This is a very good style. I like the way it resets to sane style and adds only those pieces that have to be visible. I tried to make a style that preserves most of the google styling, only changes the colours to dark but it was quite a bit of work, and not quite finished even for v1.
There are minor visual glitches - the "Search" text is partially obscured with the advanced search options, the chat dropdown is transparent
I turned down the text color and the various mail row highlight colors for my use of the style. The mali row colors are specified in two places for some reason ..
I picked some greens from the puzzle piece picture for the non-experimental addon title an author which are particularly hard to read, and quite important.
Note that if you put the style spec for all addons first you can get a default style and an experimental style without writing not[class=~exp] or what was it.
