   I agree.  This feature is still under development conceptually though - 
it's not time to code yet.  I intended to start coding it once I had fully 
documented all the requirements.  Right now I'm still developing the users of 
this, so it's quite premature.

    I'm developing the scripting side in kst/kst/extensions/js right now.  
It's still in flux.

   That may be useful, but it's not the primary goal from my point of view 
yet.  This bug report, at least from HFI perspective, from scripting 
perspective, and my perspective, is to add new ViewObjects.  These work in 
layout mode and were the original basis for designing the view object 
infrastructure.  We already have the manipulation (DnD etc) setup for it, and 
it is explicitly wanted outside of plot-space.  Since we can compose objects, 
I personally think that it is even sufficient to replace our current labels 
assuming that the user interface issue can be solved.  (Labels are 
"convenient" but inconsistent.)  In addition, anything other than View 
Objects as designed now would be completely inconsistent from KstScript, and 
well, it would throw away a month of work.

  There has also been a request from HFI to add some annotation support on a 
curve level, which is to say, inside the contents of a plot, or in plot-axis 
space.  This is something new and different and needs plenty of careful 
thinking and discussion before implementation.  It might make sense to only 
allow these sorts of things programmatically to start.  On a more global 
level, once KstScript is "done", I think we should consider reducing 
iterative UI items in favor of a cleaner interface and promoting the 
command-line as an alternative mechanism.  The UI is starting to get very 
complex.
