The current structure of pd-devel is as it is because I think the key  
to success is to tackle this problem one step at a time.  DesireData  
is a huge leap away from the current structure.  DD's structure is a  
good idea, but it was too dramatic a change, perhaps.

Anyway, what I am currently working on, and have basically working, is  
making the GUI 100% Tcl.  It is now 100% Tcl, it is just not 100%  
working yet ;).  It is now (barely) usable and there are now nightly  
builds of pd-devel-extended.

About your example, I think that we definitely should address things  
like that.  But part of the mandate that Miller, you and others have  
laid out for pd-devel is that it should not change the C code or the  
current API.  That means your example is definitely not going to  
happen in this stage of the development.

That said, it would not be hard to reduce the above commands to  
succinct messages using Tk's tagging and the "move" command.  Then the  
selection would tag everything, then you only need a single move  
command to apply to that tag.  This then could easily be converted to  
Pd messages.  So it seems to be that this should be a two stage process

First things first, this pd-devel GUI needs to get included in  
vanilla, so we need to stick to those guidelines laid out by Miller.   
And Miller, any feedback that you can offer would be most appreciated.

If nature has made any one thing less susceptible than all others of  
exclusive property, it is the action of the thinking power called an  
idea, which an individual may exclusively possess as long as he keeps  
it to himself; but the moment it is divulged, it forces itself into  
the possession of everyone, and the receiver cannot dispossess himself  
of it.            - Thomas Jefferson
