Develop My Subscriptions Playlist for mps-youtube

Mpsyt Looks And Feels Awesome,

But their is one feature i want to see even more when i am using youtube and that is
to actually login and play my subsciptions.

In this way it could work:

you type in mps: subscriptions
and first you get a login screen: Where you type in your Username and Password
now that you finished you get a full featured list of your subscriptions page                                    

wouldn't that be awesome
think about it.
