We have amended the layout of buttons within the edit quote section as follow:
1. 'ADD QUOTE' button removed.
Quote generated by choosing the price list in the 'SELECT PRICELIST' dropdown. The 'ADD QUOTE' button seemed like an unnecessary option since the 'SELECT PRICELIST' option was required anyway.
2. 'DELETE QUOTE' button repositioned to the pricing section.
The pricing section seems a more suitable place for this option.
