The plot copy is a great feature.  But, in my opinion, it should be done as a 
standard copy/cut/paste (^C/^X/^V) if this is possible.  I am not so keen on 
D&D in this case.  Most apps seem to use copy/paste to make copies of 
graphics, etc, so we should follow what people expect.

In Zoom Modes, copy coppies the mouse position into the clipboard (?) for 
pasting elsewhere.  This can stay as is.

In Layout Mode, 'copy' should copy the the current plot or group of selected 
plots into the 'clipboard' for pasting elsewhere.  Paste should paste a copy 
of the coppied plot, located at the current position of the cursor. 
I'm not sure of what gets pasted if you copy somewhere else.... perhaps the 
XML of the plot?  This way we could copy between ksts, and it makes all of 
the inheritance stuff straightforward (use the existing save stuff into a 
stream?)  

It makes copying between windows in any MDI mode straightforward.  The plot 
should be pasted with the top left corner of the plot at the current location 
of the cursor. 

In text mode, copy/paste should be used to copy labels, once we know how to 
select them.... (not now)

In the short term, you could just move the current implementation of Copy Plot 
to Layout Mode, where I looked for it as soon as I heard about it.  But if we 
can figure out how to do copy/cut/paste, I would love it.

Thoughts?
