When approving or rejecting a change order it would be helpful if you could add a file attachment to the transition comment, also have the ability to edit a comment afterward and add more attachments.
I frequently have the situation where I need to attach an email or scan to an ECO after it has been closed. An example would be an email from a customer regarding acceptance or rejection of a change (since we have many contracts that require customer approval for changes but we often decide to proceed at risk without waiting for such approval since it would impact our schedule and we are fairly certain they will agree). This kin of situation requires us to accept and close the ECO in order to release the change. Being able to attach any correspondence to an ECO, closed or not, is very helpful when researching the change later.
