Create a visualforce table showing all attachments related to an opportunity

Problem: currently when users add email to an opportunity using outlook plugin the email is added to Activity History table. If a email has an attachment it is saved under that email's record. The problem is that attachment is not added to the Notes & Attachments section on the opportunity details page. It is inconvenient, because users have to look through each email in order to find an attachment. Solution: create a visualforce table that will display all attachments associated with an opportunity: - Attachments from the Notes & Attachment section - Attachments from emails in the Activity section We are on Pro version, so we'll need a package / app.
