// Just for curiosity: post I've written to Gmail G+ Page:
Sorry, but the new design is a huge step back and I am very annoyed you've eliminated the ability to switch back to original look. To be totaly honest, I really wonder that the new design passed the usability testing. If it was even tested, of course..
I mean, what the hell were you thinking? Everything is dull and grey, there is no contrast and color between sections and controls. And at deafult, it is wasting space like there is no tomorrow. Huge buttons and wide lines, it's like iPad app, not a browser layout. And it's like an e-mail from afterlife; grey, lifeless, empty..
And don't get me started on "Themes", because they are basically useless. Seriously, what's the point of having everything in "green" or "blue", when there is still no contrast (only shades of color are a bit different). What's the point of "flowers" or "wood" or "whatever", that just put some distracting picture on background. Proper theme should change everything - sizes, fonts, spacing and so on.
I've been watching discussions and informations about the "new look" for many months and even people from Google often mentioned frequent complaints like "spacing" and "contrast" - but in fact, nothing happened and even the "final version" (which was forced upon us) is totaly the same as the optional beta from last months.
As far as I can tell, the only way to achieve at least some usability is to use maximum "compact" spacing and "high contrast" theme. But quite frankly, is still sucks compared to original. The only positive thing is, that all our messages are not sqeezed to a tiny unusable column like stream and comments here on Google+. I really don't understand your recent obsession with huge empty and useless spaces..
