Pro-Log Guild allows you to scan your guild bank and save a copy of the logs to review later.
To scan, open up your guild bank and look in the bottom left corner. You will find a button that says "Scan Bank". Click the button and wait for the addon to tell you it's finished scanning. Do not move away from the bank until this is finished or you will have incomplete data.
To open up the review panel, use the slash command "/plg".
