I think it's an improvement and would like to see it committed at some point, my only reservation is that this is an interface change and there's everyone else using it to consider. That said, the necessary user changes are trivial - if one has the OSXApplication object, one can import the module and call the appropriate function directly.


That's two interface changes in the next release (the other is getting rid of app menu groups in favor of just inserting separators). I'll reduce the shock by keeping the old interfaces around for a while, marked as deprecated and re-written to call the new ones.
