Reminder: Don't Mess With The User's Options

Just wanted to remind everyone that if a user sets an option, the plugin should not change the value of it. For example, if you have an option that accepts a selector, like "#foo" and you want to store a jQuery object from that selector, do not overwrite the option.
Good:
this.someOption = $(this.options.someOption);
Bad:
this.options.someOption = $(this.options.someOption);
