would be nice an embedded text editor for pd patches. yes, I mean an editor to see/edit the patch source file directly, and that is visually linked in both directions [source/gui], so selecting and object would locate its code in the editor, and editing the code would react the changes to the object itself.
this is more handy for some tasks, e.g. I want to re-create dynamically an object with pd-win-messages.... or insert new objects interactively by typing the code... :) (maybe I have some programs that can generate sequential garbage of text more quickly than CTRL+C,CTRL+V,edit... hehe)
more nice would be some way to access portion of memory by other programs, in order to let external C programs modify a patch in puredata.... but I think this is still "sci-fi"
all the best
