Thank you for your feedback.
Regarding site design, it is now been fixed in last update done yesterday (9.0.1). I request you to check that out. It should integrate with your theme now if you enable in setting.
I am glad to know that you ware enjoying the free version. If you need all premium features, will need to purchase.
Allow me to clarify what happened. The Email Notifications & Canned Reply were Beta Features which have now successfully been tested and updated to most robust version. It is correct that the final versions are part of the Add-On bundle, however the very affordable Add-On Bundle gives you access to many high-end features including Notifications & Canned Responses – also ability to be able to export your tickets for record keeping or various CRM tools. We remain the most affordable Plugin with highest number of advanced features with a very dedicated customer service team. Not only that, our team will help you install and configure the product should you face any issues.
