Naming conventions

Variables that contain jquery selected elements should start with a '$'.

Not:

var due = $('#due');

Do:

var $due = $('#due');

Anonymous closures

Use always, to prevent global variables:

(function () {
    // ... all vars and functions are in this scope only
    // still maintains access to all globals
}());
