I very much doubt IPB developers can create a better framework than Twitter.
The benefit of Twitter Bootstrap is that because it's so popular there is a lot of support for it - many templates already exist that give a unique look and feel plus the design is very intuitive which allows people to make adjustments and modifications very easily. It is a rock solid framework that works brilliantly across all modern web browsers and devices.
To update this for 3.2.3 simply change line 26 to:
public function boardIndexTemplate($lastvisit="", $stats=array(), $cat_data=array(), $show_side_blocks=true, $side_blocks=array())[/CODE]
And line 44 to:
[CODE] return parent::boardIndexTemplate($lastvisit, $stats, $cat_data, $show_side_blocks, $side_blocks);
