[Request] Simple PPTP VPN server plugin

I know that there is already the OpenVPN plugin, but it requires a dedicated software on the clients. I was thinking to setting up a simple PPTP VPN server on my nas, in combination to the DDNS on the router. In my opinion this would be a little more user-friendly because it is a regular VPN supported natively on quite any OS (mobile ones like iOS included). I found this guide:

and it seems really easy so I'll try to install this later, but a simple plugin to operate on the settings via the webgui would be great...
