We got some user feed back: one of their main concern when trying the studio that gives them bad feeling about it is the fact that when the execution starts, it closes the diagram then reopen them.
The location of the diagram in the workbench is lost.

It would be much better if it can simply "switch" the diagram from the edition to the animation (with the lock) state.

Note: there are several cases to take into account depending if it uses Melange resource or not.
