Looks very weird now. Also, on mobile mode i can't choose inbox/alerts directly on my iPhone now, have to click my username first. Annoying.

Staying as it is.
Consistency with the home page, and part of a wider effort to make the site a bit more user friendly.
The mobile mode is less user friendly as a result though.
Never mind.
Not for my mobile, it was so small before that my screen picked at random which button I pressed.
And I have lovely girly hands so the fat fingers excuse doesn't wash here.
Buy yourself a bigger phone DUHHHHHHHH
Is it just me or is it getting bigger by the second?
That's you.
