Fork Metamask Wallet extension -- 2

PLEASE READ CAREFULLY !!!

Fork existing Metamask wallet,

1. Even metamask is installed, both metamask must work together

For example :

from html if run :
window.ethereum.enable -> open Original Metamask
window.nizzle.enable -> open Forked Metamask means my metamask

2. Make default network my own RPC URL
At the moment original metamask default rpc URL is Ethereum Mainnet
But I want my own RPC URL must be default

3. Make simple html with button to connect to Forked Metamask not original Metamask

4. Make documentation while cloning :
which parameters will be changed.

5. Name Cloned Metamask as Nizzle
