Comment 14 for bug 481825

That *could* go into users-admin, since I can't find another place to put it. Or maybe a nautilus option in the properties of your home dir could be good. Changing the default umask is something that the system-tools-backends can do, but ATM only in /etc/login.defs, so tweaking /etc/profile and ~/.bash_profile is not really trivial to do. Then we'd also have to add support for changing file permissions, not complex, but still some work.

I won't have time to do this in this cycle anyways, but that may be an idea for later, it would fit nicely into the rework users-admin GUI.
