VMX Extras 

VMX Extras is a simple editor for the virtual machine configuration files (.vmx files) used by VMware Fusion. While it's perfectly possible to edit vmx files with a normal text editor, VMX Extras does a little bit more - it prevents you from entering the same key twice, fixes line endings, and most importantly, contains presets for a bunch of useful options. Note that these features are already present in Fusion, VMX Extras just makes it a little easier to access them.
