Store user secrets separate to general settings configuration? Or option to encrypt secrets?
I'd really like to back up my Quassel settings with the rest of my dotfiles (using GNU Stow), but sensitive information is also stored within quasselclient.conf.
How about storing this data in a separate file so that it can be blacklisted from being uploaded?
Alternatively, another idea could be an option to encrypt the sensitive data and ask for a password on each client start.
