The problem is that to make the update method of widget class work, the name inputs on the form method should be set via $this->get_get_field_name(‘name_of_the_field’); but wp_category_checklist has no argument to setup the name of the inputs (checkboxes). However, wp_category_checklist uses a walker class to print the checkboxes and allow customizing it. By default the … Read more
I think WordPress widgets create li tags on default. If you want the bullet points removed you could fix that with a css approach. .widget li { list-style: none; }

The default Recent Posts Widget code is in includes/default-widgets.php but you should not be hacking Core code. Copy that function to your theme’s functions.php, rename it, and create your own customized widget.

Edit Quick-and-dirty, using the bare-bones Widgets API class example: <?php class wpse48337_Widget extends WP_Widget { public function __construct() { // widget actual processes } public function form( $instance ) { // outputs the options form on admin } public function update( $new_instance, … Read more
