Hello Kevin,
Many thanks for your contacting us. I am Vincent, working as Senior Account Manager and Consultant at Cmsmart. My pleasure to support you in this case.
First I just want to know if this plugin is compatible with Joomla 3.9.5 and Virtuemart 3.4.3
=> yes, our product is compatible with JM 3.9.5 and V.M 3.4.3

Also I was wondering if it's possible to display the attachments differently. For example, showing a general name (like Manual) which can be changed in the back-end rather then showing the file name (User_guide.pdf)
=> I am so sorry to say that currently our product does not support this feature. However, we can customize it for you to get an extra development with an extra fee. Let me know if you want to get it, i will send you details of quotation for this task.

If you have any questions, feel free to let me know

Regards,
Vincent
