"Cooked" mode in Designer

The cooking process makes the reactivity of a graph significally slower than its "cooked" counterpart (sbsar running in other app than Designer). This makes the process of testing a graph (editing its parameters) much slower in Designer than in other platforms. I would suggest to add a "cooked" mode in Designer that would enable to test our graph with the best performance, provided the graph would not be editable in this mode.

An alternative could be to open the cooked version in another app (Viewer?) with a single button click. I would like to avoid the tidious process of building the sbsar then opening another app and opening the sbsar.
