Yes, I think so as well. There are some problems inside libapt that
makes this a bit clumsy sometimes (libapt is not really designed for
interactive use). We have a function in the policy engine of apt to
create a pin, but not to remove it (which is importend if we want to
chage the default release without rereading the whole cache). I'll ask
on the debian-deity ML and Gustaco and see if we can get something
like this. 

I know that the "release" scheme is more flexible than just having
"stable/testing/unstable" :) My problem was that I wanted to see if it
works and I have no idea right now how I can make libapt to tell me
what releases are available (and what origions, that might be nice as
well). Do you have any idea Panu? Or maybe Gustavo?

I thnk #2 is not easy. We might add a "advanced" tab or something like
this to the main information notebook. And we have the idea of
Sebastian to add a radio button group. I'm uncertain what way to
go. #1 would be enough IMHO when it would be possible to change the
default distro without rereading the cache.
