jQuery.checkboxShiftClick
This single-function plugin can be called to add this functionality to any number of checkboxes. By default (onload) it's applied to all  elements that have a type of checkbox, excluding any with a class of 'noshiftselect'. As it has a built-in prevention to avoid binding the CheckboxShiftClick twice to the same element you can simply run the line below under "Default" again at any time if you want to enable dynamically added checkboxes in the page to be shift-selectable as well. Or alternatively run it on the specific selector of choise (see second example below).

jQuery.placeholder
This plugin adds support for placeholder texts in input fields for browsers that don't support the HTML5 attribute yet. If the attribute is not supported it's applied to all input elements with a 'placeholder' attribute, on-load.

It has a built-in check for browser support, but for effeciency it's best to do this check (also) wrapped around to call.

There are several prototypes for older browsers serving as backwards-compatibility for new native prototypes in newer browser. Also several other convenience functions have been added.
 * trimLeft: Trims whitespace from the left side of the string
 * trimRight: Trims whitespace from the right of the string
 * trim: Trims whitespace from the both ends of the string
 * ucFirst: Returns the string with the first character capitalized
 * escapeRE: Returns a string for literal use in a regular expressions by escaping characters that have a special meaning in a regex.
 * isEmpty: This function checks if a variable is empty. Supports strings, booleans, arrays and objects. The string "0" is considered empty. A string containing only whitespace (ie. " ") is considered not empty.
 * compareArray: Compares two arrays and returns a boolean for whether they are in fact the same
