Thanks, otheriz & rahul for replay.
Can you suggest how we can do customization without a touch of the core process.? like, is there a way we can extend package in child package (as in Magento) so core functionality will not effect?
Else it will be very hard to replicate customize work in the new version. Thus it will better to not update the Bagisto at my end and can do further customization. So can you suggest the way to stop Bagisto updation by composer permenently?
Please guide o this.
