Safer Permissions
The first one is Safer Permissions.

I am logged in as user/1. As you can see, even I can’t assign potentially malicious permissions to anonymous users. The original purpose of this module was to make spammers’ life harder on Gardens, but I think there are other cases when this module might be useful. As an agency, it might be a good idea to install this module when the customer asks for the user/1 account.
Advanced Syslog
The second one is Advanced Syslog.

This module is a replacement to the core syslog module. In the screenshot, I show the difference between the admin interfaces.
The module might come in very handy when you suspect that a module is malfunctioning. You can increase the log level for that one module only, and your syslog won’t be spammed with info and debug messages of all other modules.
Advanced Syslog overrides the core syslog module by default. You can turn this behaviour off, but you will most likely experience duplicate log messages.
