This idea has been merged into another idea. To comment or vote on this idea, please visit S1-I-1199 More information on Audit Trail list.
AUdit trail doesn't show quotes etc (not even a summary of it), so unless the customers CC themselves on the email when they email the quote - they might lose it, especially if they delete it by mistake. An audit trail, as the name states, should show everything done in the account, even if just a summary of it.
