• Allow restoring from paths with symlinks in more situations (including a fix for a backup error when ~/.cache is a symlink)
• Treat operation dialogs more like real dialogs (modal to preference window, with correct styling on default buttons)
• Try harder to stop running duplicity commands when we are terminated
• Don't hide an error message when also running our bimonthly backup verification
• If there isn't enough space in the backup location, tell the user how much is needed
• Exclude flatpak cache directories by default
