Describe the feature

From what I know, the WireGuard config is just a loopback to the localhost to bypass iOS restrictions. However, since on iOS only one VPN profile can be active at a time, and I need to use Tailscale for my work, I won't be able to be connected to the WireGuard profile usually.

Hence, the ability to customise this IP for the signing server would be good, as I can simply change it to my device Tailscale IP, which should achieve the same effect of a loopback with WireGuard.

Thank you.

Use cases

• Usage of SideStore with Tailscale
• When there are multiple VPN configs on device (the user cannot connect to more than one at a time, because of limitations of iOS)

Alternatives

• Another alternative is to add Tailscale integration directly. However, this would be much more difficult and elaborate than if the IP was just user-customisable.
