PDF export profiles shall store all settings
Until now, coming from CS2, Indesign was not able to store the security settings in a PDF export profile. Every time when exporting a PDF I have to set these settings manually, plus the password. I know I could do that in Acrobat with an action, but that's only worth doing when exporting more than two files at once. The same PDF profiles could also be used by Distiller when converting EPS to PDF by drag 'n drop, so the target PDF would always be password protected. I call this automation.
