Want to show or hide widgets on specific pages? This is a great little snippet contributed by Joel Worsham that will do just that. You will first need to get the id name of the widget that you wish to define. You can do this be viewing the page source or using a web inspector tool to view the widget id. The current sample is setup to only display the core ‘pages’ widget on the contact page only. Don’t forget that
is_page also accepts an array of page names and id’s.

Have you ever wanted to change the default options when inserting media into a post? Setting the default alignment to “left” or the default size to “large” ? This may not appear to be a big deal but if you are constantly changing the settings to the same thing over and over again for each image this is a must have snippet. We are updating the options “image_default_align, image_default_link_type, image_default_size”. Keep in mind that this just changes the default settings of these options within the add media popup.

$before. Move is the name of the column you would like to move. Before is the name of the column you would like to move it before. The following snippet will let you move the author column before the post title column.
