I'm known to put great emphasis on graphical perfection, and as such I
have to say that the possibility of having proper animation in the
playlist is absolutely crucial. It has been a design goal of the
playlist from the beginning of Amarok 2 development. Even if we don't
get animation done until 2.0 anyway, what use would it be to switch to
a new system if we have to change it back later?

So I would like to see proof for the feasibility of this before
agreeing to switching.
