Quick note: Occasionally the LessWrong team makes announcements, or posts like this one that are intended as a longterm reference for how LessWrong works. Those posts might sometimes be set to "frontpage", which is a bit of an exception to the "no meta on frontpage" rule. Just wanted to flag that this an explicit exception sometimes made for key site information.
In the next two tabs Config and Template you can set individual properties overriding the global settings of the app instance configuration. To do so, just uncheck the box before the property and new options like radio buttons or dropdown fields will appear. Here you can choose your favorite settings for the frontpage. In our example the latest created item will show on top of the other ones and the frontpage will show the categories in two columns.
