Idea #218: More simple GUI key gpg repository

I am a supporter of the GUI.
When adding a repository via GUI and then you have to add a key gpg (always via GUI) is very uncomfortable. We must insert the key link in a browser, download the key to a file and then add the key via GUI.
Here a video: http://it.youtube.com/watch?v=5jSw8BrtjIk
I think that is easier to enter the URL in the first screen and get the key. I do not think it is very difficult to achieve. What do you think about?
I apologise for my English (Google helped me;)
