I thought it would be very useful to have an extra button beside each email template on the "Setup" -> "Email Templates" window that shows whether the template is currently enabled or disabled. Clicking on the button would then enable or disable it depending on the original status.
This is only a really minor thing, but could save an enormous amount of time.
On a slightly different topic, I'm new to WHMCS and am just getting acquainted with it. Is there a reason why there are so many duplicate email templates or could it have been an error during installation. I cannot delete them through the control panel as these were set up during installation...
Great product from what I've seen so far!
