[feature request] Archive the (optional) flag and (un)read status

[jicho]

Hi,

I'm (finally) playing around with Mail Archiver, it really looks good and works nicely.

Is there a change you will add the option to store the flag "boolean" for e-mails and the (un)read status?
It would be nice to have this data in my archive and it would also be nice to restore this info to existing and/or deleted emails :)

With this addition you would really have a backup of your email.

I'm not sure if a feature like this is completely in the scope of Mail Archiver, but it would be nice to have.

Thanks for your work,

Eric
