First I would like to thank you for all the awesome work you have done for dojo. My question is regarding the new command/action architecture you want to implement (which looks a lot like eclipse’s RCP command/action plugin stuff): First, will these commands be undoable, with something like canUndo and undo methods? Also, it seems like the current undo stack is maintained by the document, since you call its execCommand method to do all the work…so where you thinking about just pushing all the commands onto your own stack? Or perhaps there is a way to push your commands onto the document stack..?

cheers,
