Is there any chance you might be able to recreate the good old grey bar of which I absolutely loved while playing dot hack G.U. which would store the run options, properties and settings derived from within the item in the seeker.
I think this object is just what the world needs from the next evolution of dock.
But, I don't wan't to impose too much though as I don't know the limitation of the code.
I'm not a programmer, just a graphic artist.
And a continuing supporter of this wondrous gift you've made.
