This plugin will re-add the “Purchased Items” column which was removed in WooCommerce 3.0. Order information is loaded via Ajax when the button is clicked. Saving resources on each page load.
After updating WooCommerce to version 3.0+, you may notice that the “Purchased Items” column is no longer in the orders list. The reason for removing this column was to save resources (each time the orders page is loaded, it was loading every order to create the query). To fix this issue, we created this plugin which queries the order data only when you click the “View Products” button.
The quantity and product name will be listed for an order when the button is clicked.

The most flexible and complete solution for your WooCommerce webshop to customize your order numbers!
By default, WooCommerce uses the WordPress post ID of the order, which result in gaps between the order numbers. With this plugin you can configure the order numbers to have consecutive counters. Furthermore, the order number can contain the year, and the counter can be configured to reset each year.
The number format is a simple string, where # indicates the counter. 
To get order numbers like “WC-376”, “WC-377”, “WC-378”, etc., simply set the format to “WC-#”.
The plugin comes in two flavors:
<ul>
<li>This free basic version, which provides sequential numbers and allows arbitrary text (prefix / postfix) in the numbers</li>
<li>The paid advanced version, with lots of additional features:
<ul>
<li>Counter formatting: initial value, counter increments, number padding</li>
<li>Flexible counter resets</li>
<li>Lots of variables to be used in the formats
<ul>
<li>date/time: year, month, day, hour, etc.</li>
<li>address: customer country, zip, name, etc.</li>
<li>order-specific: Number of articles, products, order total etc.</li>
<li>product categories, shipping method</li>
</ul>
</li>
<li>Custom variable definitions (with conditions on available variables)</li>
<li>Multiple concurrent counters (e.g. numbering per country, per day, per ZIP, …)</li>
<li>Different order numbers for free orders (e.g. “FREE-01” for free orders)</li>
<li>Different number format for e.g. certain IP addresses (for testing)</li>
<li>Different number format depending on products, product categories, shipping classes</li>
<li>Customize invoice numbers (only for the “WooCommerce PDF Invoices and Package Slips” plugin)</li>
<li>Different numbers depending on vendors (WC Product Vendors, WC Vendors and YITH WC Multi Vendor plugins)</li>
</ul>
</li>
</ul>
