Hi Mary
>> having the "home" button directly below the ATP logo seems kind of redundant,
Just a guess, but maybe the explicit Home button is for absolute newcomers who haven't noticed that the logo is clickable.
Here's a wacky idea that would probably look horrible to normal people: put the skinny menu bar over on the left, SIDEWAYS and make it float in the left-hand column so it was always visible. Then maybe shrinks the width of the left column.
Then we would all need chiropractors from twisting out necks 90 degrees sideways. Besides, if floating horizontally is not uniformly supported by mobile apps, floating sideways would be even less likely to be supported.
