besides get/putCustomOptions, is there a way to access the Photoshop's registry?
I'm wondering whether it can be considered a safe place to store sensible information (like serial numbers and commercial software registration data) or not.
It would not be a good idea, as a reset of the preferences would wipe out all the information.
Well, that would be an annoyance - I'd have liked to avoid writing a cryptografied file on disk, though.
