berk-kucuk/entropy-shield ? reverse-engineered prompt

Build me a Linux privacy app with a clean desktop GUI that lets me turn Tor, DNSCrypt, I2P, and Tor hidden services on and off from one place.

I want it to feel simple for a normal user, with a system tray, connection status, notifications, and a few nice themes. It should be able to route all traffic through Tor, protect DNS so it does not leak, start I2P, publish a local folder as an onion site, and include a kill switch so everything shuts down safely if a service drops. It should also support opening one app through Tor, and have a privacy focused browser setup for Tor and I2P. On disconnect, it should restore any system changes it made. Look up current docs online if you need to, especially for Linux networking and service management.
