Currently the linux client have several interested features that could be great to have in the GUI.

For example be able to connect to fastest secure core server, or random secure core (--random -sc), random p2p, etc.
It could be an option to click connect, like the other ones, or a param that could be added in the Autoconnect or Pinned tray icons, like the already existing "Fastest" option.

For example:
1. SecureCore -> --securecore
2. Random -> --random
3. RandomSecureCore -> --random --securecore
4. P2P -> --p2p
5. RandomP2P -> --random --p2p

Only the GUI because it has support for Advanced kill-switch would be great to be able to connect to a random and decongested server. Proton have server in countries that usually are lower than 5% of capacity while others are +60%.

It would be a good option for people like me that only want to connect to a sever without worrying where it is.
And like these servers are less used, the IPs are usually less blocked by services or bot scanners.

Options:
--country TEXT Connect to fastest server in specified country
Country code (US, GB, DE) or full name ("United States")
--city TEXT Connect to fastest server in specified city
City name (use quotes for multi-word: "New York")
--p2p Connect to fastest P2P-optimized server
-sc, --securecore Connect to fastest Secure Core server
--tor Connect to fastest Tor server
--random Connect to random available server
-h, --help Show this message and exit.
