Is the UI toggle simulation controls actually used? (Spec 2)

[hernanmd]

The toggle simulation controls in the UI complicates the implementation logic in the current version:

• This spec widget is always "opened". It only changes its visible state.
• When a project is closed, the input values inside this widget should be cleaned, without destroying the window.
  • If destroyed, rebuilding this specific widget inside its spec container is another complication.
• When the controls are specifically hidden by the user (without closing the project), the state of the inputs should be preserved.

Is there a use case or specific need in the toggle simulation controls (show/hide) feature?

This feature is not required and can be deleted in a next release when everything is migrated to Spec 2
