Chart & Workspace Questions

Greetings,

1:

Is there a way to move a chart from one workspace to another? Detach does not seem to allow that, as the detached chart automatically gets reattached if you try to switch workspace. There seems to be no way of simply copying / duplicating a chart including the objects from workspace 1 and move it to workspace 2 (or in web version for that matter)?

2:

Is it possible to add a confirm prompt to the close chart x in the corner of the chart (seeing as all objects will be lost if it is closed accidentally).

3:

Is there a measurement tool somewhere that can show % change? I know the crosshair does not show % change, the risk reward tool does but that is a rather clumsy way of taking a simple measurement.

Regards.
