The ability to create one master password to access the password file(s) of encrypted files on your system/network.

The ability to create one master password to access the password file(s) of encrypted files on your system/network would be useful. True you do offer the ability to make and use a binary key for decrypting files but that means all files must have the same key sequence to be decrypted whereas with a master password (or even a master binary key) to pull your password(s) file(s) only you can safely create multiple password keys for multiple projects and still have the means to recall passwords that may have been forgotten, or use the files to make sure you haven't repeated a password on two or more files.
