I don't remember
exactly what the old format looked like, but I can sympathize with the preferred layout and usage on desktop/laptop usage; I almost exclusively post from those devices. That said, the default style of the new layout leaves a lot to be desired from my perspective -- there's entirely too much wasted real estate.
BUT... the good news is this is user-fixable. If you head to your Account Preferences, you can create/edit a custom theme.
There's a lot of options here, but the one you care about is this one:
- maximum page width (1,000 to 2,000):
(Make sure you save the style after changing the value)
Set that value to 2,000, and it will widen the screen for you -- this has a flow-on effect of widening those columns, which means less blockiness. As a bonus, since it only affects the
maximum page width, it won't screw up your styling when you do view the site on a smaller screen.
