Currently, there is only one module setting.

"Remove module settings when un-installing modules?"

• Yes
  
• No
  
  

This basically does what it says, it removes any previous settings you may have had with the module when you decide to uninstall/remove the module. This is an excellent tool for troubleshoot, if you are having problems with a installed module.

Sometimes a module may have a bug in which a certain setting causes it to crash the site or features of that module. With this setting, you will not have to enter the Database and remove it manually to restore your site.
