As the author, I use those classes in a lot of the forms I build, in a variety of ways, on my client projects.
I usually do something similar to the code fragment below for processing forms; this should reveal how to easily delete items, with a delete confirmation step/form (please note this is not complete functional snippet code, just some fragments showing some possibilities):
<?php
//INITIALIZE AND LOAD DATA AND THE MAKEFORM CLASS HERE
// (left out for brevity)
// set some required fields
$requiredFields= array (
'Username' => 'web_users:user_name',
'Password' => 'web_users:password',
'Email address' => 'web_user_attributes:email',
'First name' => 'person:first_name',
'Last name' => 'person:last_name',
'Expiration date' => 'member:expire_date',
'Street address' => 'address:street',
'City' => 'address:city',
'State' => 'address:state',
'Zip' => 'address:zip',
);
$invalidFields= array ();
$deleteConfirm= false;
if (isset ($_POST)) {
if (isset ($_POST['save']) || isset ($_POST['save_x'])) {
foreach ($_POST as $post_key => $post_val) {
if (empty ($post_val) && $key= array_search($post_key, $requiredFields, true)) {
$invalidFields[$post_key]= $key;
}
}
if (empty ($invalidFields)) {
// DO YOUR INSERTS/UPDATES/ETC. HERE
// (left out for brevity)
} else {
$modx->setPlaceholder('messagebox', '<p class="warning">' . implode('<br />', $invalidFields) . '</p>');
}
}
elseif (isset ($_POST['delete_confirm']) || isset ($_POST['delete_confirm_x'])) {
$modx->setPlaceholder('messagebox', '<p class="warning">You are about to delete this subscriber! Clicking Delete this below will remove this subscriber from the database permanently.</p><br />');

And a full page view of the listing is just a matter of creating a target page where you pass a unique identifier from which you can retrieve the data and present it however you so choose.
