Thank you for your precious feedback. We appreciate all kinds of feedback from the users of "Depilex Salon - Parlour - Spa - Gym - Multipurpose WP Theme". Just to make things clear, we want to share our views also.
1. The 1st Complain "footer wasn't editable, so manual customisation is necessary"
If the footer isn't editable, what are the options there in the 'Theme-Options' panel? The 'Theme-Options' panel got a separate page only to edit the Footer content as needed. (Screenshot is here)
2. The 2nd Complain "Issues with woocommerce (blank page, so I have used the support, who does the job)"
You updated your WooCommerce plugin before updating the theme. Whenever WooCommerce got an update the themes need to update some codes to match with the updated version of WooCommerce. And, as you said 'The Support Does the Job'. Yes, you contacted us and we updated the theme for you to solve the issue. The support team helped as required, still unhappy :) ???
3. The 3rd Complain "Issues with mouse scroll in woocommerce because of the smooth scrolling option".
There is a Switch in the 'Theme-Options' panel to on/off the Smooth Scroll (Screenshot is here). So easy to switch it Off if any of your plugin got an issue with that.
However, we thank you once again for your precious feedback. We will work harder to make our themes better and better.
