Hello @Saurabh
I have few suggestions for future version of Foodomaa. If possible in future consider these.
If possible move that switch between delivery and self pick up below the coupon code or above bill details and make radio buttons like selection instead of pop up.
Same for Order schedule. If order schedule module is enabled than make it required field. User have to choose ASAP or schedule the order for later.
As you are not working on SAAS version so please consider making Order schedule's time slots as editable. Allow admin to create time slots of 10, 15, or 30 mins.
These are just suggestions. If possible please consider for fututre versions.
Thanks alot.
