I want to switch to Proton Unlimited, but what's s stopping me is thier very basix VPN app on Linux. I currently pay for mail plus, Simplelogin and Mullvad, probably gonna upgrade to yearly proton unlimited and still use mullvad. Mullvad's killer feature on Linux is app-based split tunneling, is there a way to do it with standard wireguard on Linux?
