Sugestion / request on the new SSL functionality

Thanks a lot for this Guys, you are awesome! I would like to suggest a future enhancement with a system setting to force HTTPS, this could either just disable the port 80 endpoint so it is not accessible, or forward the user to the HTTPS version of the requested page automatically... whatever you think its better... It would also be great if you could add the ability to upload your own certificate. Thanks!
