Reorder Layout Tabs, Lock extra viewports to specific view and hide/show curve

I can open two extra windows now I have upgraded to Pro but they keep switching views on me.

[ul][li]I would like to be able to pin a extra viewport to a specific view per window. [/li]
[li] It would be very helpful to be able to drag and drop layout window tabs to reorder them.[/li]
[li]Hide/Show curve handles. When dealing with many points close together it can onerous to deal with handles and points[/li][/ul]
