Doesn't matter what changes you make, you'll never please everyone.
I like the less busy layout of the HTML reports. The font size/style doesn't make much difference to me. And I'm in the "older and not as great as it used to be" eyesight crowd.
They make iOOTP for mobile devices, full OOTP for laptops/desktops. That's hardly substantiation for arguing banner size.
The rest of your points are good, but most of that stuff comes down to personal preference again, and as previously stated, you just can't please everyone. I guess the real solution would be to give the user a choice of 2 or 3 fonts/banner sizes/etc somewhere in preferences, but then I know nothing about programming so that may not even be possible.
At the end of the day, hopefully Markus & Co can find a happy medium.
