Some of the producers that use the platform have requested the have just the "Make Offer" button for each beat without any other licenses. This forces the customer to make offers generating sales. (That's the idea anyway)
The new code will check if there is no priced licenses, but still make offer is turned on then it will show the + icon
This is not a proven method but it's there if you want to use this option. Some producers are using this with some success, but again this method may not be for you.
