Any operation (invoice, bill, etc) should have a preview button that will list what the journal entry will be.

Examples where I or my bookkeeper use it:

• in invoicing, they want to make sure the exchange rate is ok so that it matches the amount on a statement

• in payments / credits / invoices

• useful to see what an operation/zoho feature will be doing in the journal

This is a must and a blocker for me (and my bookkeeper) until this feature is included.
