Hello rev,
This is set as a text input and there is no built-in option to change it to a textarea.
That being said, if you’re comfortable with modifying the template, the plugin does come with a feature that lets you customize any of the included layout templates by creating your own template files. This is mostly meant to allow you to code your own customization for the front-end output. However, we do include templates for the order edit screen, which can be customized as well.
This would give you a non-destructive way to make the change you want. To do this:
1. You can get to the templates folder by opening your site via FTP and navigating to /wp-content/plugins/order-tracking/ewd-otp-templates
2. In that folder, you can find the template file you would like to edit and download it to your computer.
3. Modify the file with the updated or new code you would like to add.
4. In the root folder of your active (child) theme, create a new folder called “ewd-otp-templates”
5. Upload your modified file to this folder in your theme.
The plugin will automatically use any templates with the same name found in the “ewd-otp-templates” folder in your active theme.

The process is the same for the Order Tracking plugin. The only difference is the name of the templates folder. For Order Tracking, it is: “ewd-otp-templates”
And the template you would want to modify is “admin-order-form.php”
