Some websites require access from certain country to work and it is annoying to always manually switch the server country while it also changes country for other websites (which may be unwanted).

To improve this, allow VPN extension user to define per web site (and per app - for a VPN desktop: https://protonmail.uservoice.com/forums/932836-proton-vpn/suggestions/50600438-split-tunneling-select-which-app-connects-through ) rules so user can select VPN server country for any defined website/app. Maybe such config. section can be combined with existing "split tunneling" section.
