Add a right-click option for jumping to an invoice/bill that a transaction refers to.
Similar to how you can right-click and jump to the other account that a transaction refers to, but have another option to instead be able to jump to the invoice/bill that the transaction refers to.
This feature request has been implemented somewhere in the 3.x gnucash series.

Note there will be a slight behavioural change in the 4.x release:
In 3.x one could click on any transaction in a Accounts Receivable or Accounts Payable account (regardless whether the transaction is for an invoice or payment).
This had two issues:
* payments can refer to more than one invoice. That case is not handled very well.
* jumping from an invoice transaction starting from an income or expense account wouldn't work.
The new behaviour is that you can click on any split of any invoice transaction, regardless of the account register that happens in and jump to the associated invoice. But you can no longer click on a payment to jump to the invoice(s) it pays. This would need more work. Note the mapping between payments and invoices can be retrieved from the owner reports (Vendor or Customer report). Particularly the new owner reports in gnucash 4.0 will have optional extra columns that are particularly helpful in this context.
