The guys on IRC recommended me to post this here so here goes:
A feature to sort the incoming files in a per-user directory fashion would be nice, i.e. same way you can log into different directories based on user email, it would be nice to have an option to enable sorting the incoming files into directories in a similiar way.
(Also, not related, but how about a more senseful way of naming the logfiles - as in, "2004-04" instead of "<localmonthname> 2004"
