I see some discrepancy in plugins' tabs & menus:

(3.1+) If you want to add multiple links for your plugin, you can use the optional parameter action:

PHP Code:

add_action('xxxxxx-sidebar','createSideMenu',array('your-plugin-filename','Menu Text', 'my-action')); 


This way a new parameter action=my-action is added to the link and you can determine which link was clicked.
(...)
main function (here hello_world_show) would look like this:

PHP Code:

function hello_world_show() {
  if (@$_GET['action'] == 'setup') {
    ...
  } else if (@$_GET['action'] == 'show') {
    ...
  }
} 


Except that no action in $_GET is ever created. Rather $_GET gets an empty my-action key. That given, proper code to handle multiple actions would be something along these lines:

PHP Code:

function hello_world_show()
{
    if( array_key_exists( 'show', $_GET ) ) {
        ...
    }
    elseif( array_key_exists( 'setup', $_GET ) ) {
        ...
    }
    elseif( array_key_exists( 'my-action', $_GET ) ) {
        ...
    }
    else {
        ...
    }
} 


Unless this is a bug that needs to be patched, am I free to go ahead and correct it?
