I personally wouldn't cite margins as the biggest visual flaw, but rather alignment in general, followed by contrast. The very first screenshot on the page is a very awkward dialog: http://library.gnome.org/misc/release-notes/3.2/figures/gnome-online-accounts.png.en http://library.gnome.org/misc/release-notes/3.2/figures/gnom... * "Use this account for" runs uncomfortably close to the account list. It looks bad. Couldn't they just put that whitespace on the right to use? * The switch labels (Mail, Calendar...) are aligned with the Email Address label, but the switches themselves aren't aligned with the email value (ovitters@...). The implicit grid is broken. * Someone was too lazy to style the email address in the selected state of the account list (dark gray on medium blue). There's not enough contrast to easily read it. http://library.gnome.org/misc/release-notes/3.2/figures/gnome-contacts.png.en http://library.gnome.org/misc/release-notes/3.2/figures/gnom... * This is the Contacts app whose sole purpose is to view a person's details. Why are their only details (Away, mail@example.com) the tiniest words on the screen? * Letter placement in the contacts list (A, C, D) looks reckless and noisy. Horizontally, its margins are not equal. Vertically, it appears arbitrary. It would look better if they were horizontally centered and vertically on the baseline of the contact's name. * The letters (A, C, D) also have too much contrast; they should be lighter. They're a visual hint, not an area of focus. http://library.gnome.org/misc/release-notes/3.2/figures/file-save-dialog.png.en http://library.gnome.org/misc/release-notes/3.2/figures/file... * Why is the filetype selector only wide enough to show "PDF Docume..."? There is a ton of space. http://library.gnome.org/misc/release-notes/3.2/figures/color-management.png.en http://library.gnome.org/misc/release-notes/3.2/figures/colo... * None of these buttons have enough padding around the label when compared to the buttons in other dialogs. * Why are the lower buttons all squished together? Most of these can't be fixed by theming, because they were caused by the dialog creators themselves. In short, there is a lack of attention to detail. :)
